# Fortunebound Game Concept Spec

Version: 1.0  
Date: 2026-07-04  
Status: Concept spec for MVP validation

## 1. Executive Summary

Fortunebound is a whimsical fantasy social-casino RPG builder for players who enjoy Coin Master-style spinning, Candy Crush-style approachable progression, and Slotomania-style reward anticipation.

Players rebuild a floating kingdom by leading a party of collectible heroes through chance-powered rituals: a reward wheel, hero-themed slot reels, and fast poker-hand raid encounters. The familiar spin-and-win loop stays simple, but every outcome feeds visible RPG and builder progress.

The game is social-casino only. It uses fictional currency and entertainment-only chance mechanics. It must not include wagering, cash-out, external prize redemption, real-money gambling, or advertising that promotes real-money gambling.

## 2. Product Pillars

### Chance With Purpose

Every spin, reel result, and poker hand should advance at least one long-term goal: hero growth, kingdom restoration, raid readiness, event progress, or guild contribution.

### Friendly Rivalry

The social loop should create playful revenge and bragging moments without making losses feel punishing. Raids can steal limited loot or damage repairable structures, but shields, recovery bonuses, and comeback events prevent harsh setbacks.

### RPG Identity

The main differentiator is not "more casino games." It is the feeling that the player is building a unique party of heroes whose powers change the meaning of chance outcomes.

### Cozy Spectacle

The tone is bright, magical, and readable: tavern rituals, enchanted reels, floating islands, expressive heroes, and colorful building upgrades. Casino mechanics are framed as fantasy games inside the world, not as real gambling.

## 3. Target Audience

Primary audience:

- Coin Master players who enjoy spins, raids, village upgrades, collection pressure, and revenge loops.
- Slotomania players who enjoy slot spectacle, reel anticipation, streaks, and event ladders.
- Candy Crush players who prefer low-friction sessions, bright progression, and easy-to-understand goals.

Design implications:

- Sessions should work in 2-5 minutes.
- The first minute must show the connection between chance outcomes, hero power, and kingdom upgrades.
- UI should use big readable rewards, clear progress bars, and limited simultaneous decisions.
- Losses should create "one more try" energy, not anger.

### Moment-To-Moment Loop

1. Spend energy to spin the Wheel of Fortune.
2. Receive resources, raid tickets, shields, hero energy, or slot tokens.
3. Use slot tokens on a hero-themed slot machine to charge hero skills and trigger boosts.
4. Spend raid tickets to enter an asynchronous raid or boss encounter.
5. Resolve the key attack moment with a quick poker-hand choice.
6. Spend winnings on kingdom restoration and hero upgrades.
7. Claim event progress, guild contribution, revenge targets, and next-session goals.

### Three-Minute New Player Read

By minute three, the player should understand:

- Spins create resources.
- Slots charge hero powers.
- Poker hands make raids feel interactive.
- Heroes improve future chance outcomes.
- Kingdom upgrades unlock new areas, bonuses, and defenses.

## 5. Core Systems

### 5.1 Wheel: The Heartbeat

The wheel is the universal entry action. It should be fast, celebratory, and low-choice.

Primary rewards:

- Coins: spend on kingdom buildings.
- Materials: repair and upgrade specific district structures.
- Hero energy: starts or accelerates hero-slot sessions.
- Raid tickets: start asynchronous raids or boss attempts.
- Shields: protect against incoming raids.
- Wild sparks: flexible event currency.
- Jackpot wedges: rare large rewards, always fictional in-game value only.

Design notes:

- The wheel should include a visible pity/progress meter for rare outcomes.
- Wheel results should occasionally chain into slot bonuses or raid opportunities.
- The wheel should never imply cash value or external prize value.

### 5.2 Hero Slots: The Power Engine

Slots are not just reward generators. Each hero has a themed slot board that charges their abilities.

Example hero-slot identities:

- Ember Chef: flame symbols charge area damage and bonus coin multipliers.
- Bramble Knight: shield symbols charge defense, revenge protection, and structure repair.
- Lyra Luckstring: harp symbols improve wild-symbol odds and event token drops.
- Nixie Navigator: compass symbols improve raid scouting and material targeting.

Slot output types:

- Skill charge: fills hero abilities used in raids and bosses.
- Combo bonus: matching hero symbols creates temporary multipliers.
- Party resonance: matching symbols from multiple equipped heroes grants team effects.
- Event marks: limited-time symbols advance seasonal reward tracks.

Rules:

- Slots consume hero energy or slot tokens earned through play.
- Paid purchases can grant more energy, but cannot create external redemption value.
- Rare streaks should show progress and celebration without implying financial winnings.

### 5.3 Poker Raids: The Interactive Risk Layer

Poker is used as a quick raid/boss resolver, not as a stand-alone gambling table.

Encounter flow:

1. Player spends a raid ticket.
2. The game scouts a rival kingdom room or boss weak point.
3. Player receives a 3-5 card magical hand.
4. Player chooses to keep, swap, or empower cards using hero skills.
5. Final hand determines attack strength, loot bonus, shield break, or defensive counter.
6. The result is resolved instantly with clear visual feedback.

Hand examples:

- Pair: basic strike and standard loot.
- Two pair: bonus building damage or repair bypass.
- Three of a kind: hero skill refund chance.
- Straight: chain attack across multiple structures.
- Flush: elemental surge based on equipped hero color.
- Full house or better: cinematic raid moment and event bonus.

Design guardrails:

- Poker uses fictional in-game cards and fantasy effects.
- Players do not wager currency against other players.
- The poker moment should feel like a tactical mini-decision, not a casino table.

### 5.4 Kingdom Builder

Players rebuild floating districts, each with visual upgrades and passive bonuses.

MVP districts:

- Hearth Harbor: tutorial district; unlocks basic buildings and daily wheel upgrades.
- Starfall Market: economy district; improves coin and material storage.
- Rune Ramparts: defense district; improves shields and raid recovery.
- Guild Grove: social district; unlocks guild bosses and gifting.

Building categories:

- Landmark buildings: required to unlock new districts.
- Utility buildings: improve economy, energy, or reward multipliers.
- Defense buildings: reduce raid damage and improve shield value.
- Cosmetic buildings: personalize the kingdom and support monetization.

Upgrade goals:

- Every upgrade should visibly change the island.
- Each district should take several short sessions to complete.
- Completed districts should unlock new hero shards, event access, or slot themes.

### 5.5 Hero Collection And Progression

Hero acquisition defaults to shards, quests, events, and progress meters.

MVP hero roster:

1. Ember Chef: damage, coin bursts, flame combos.
2. Bramble Knight: shields, repairs, revenge resilience.
3. Lyra Luckstring: wild symbols, streak support, event drops.
4. Nixie Navigator: scouting, material targeting, raid route bonuses.
5. Pebble Oracle: pity-meter boosts and chest reveals.
6. Mallow Medic: recovery, guild healing, failed-raid consolation.
7. Zephyr Jester: wheel re-spins and bonus wedge manipulation.
8. Gilda Gearsmith: building discounts and slot-machine upgrades.

Post-MVP expansion:

- Add 4 more heroes for a 12-hero season-one roster.
- Introduce hero relationships that create party resonance bonuses.
- Add hero skins as monetizable cosmetics with no direct cash-out implication.

Progression structure:

- Star level: unlocked by shards.
- Skill rank: upgraded through hero scrolls.
- Affinity: earned through repeated use and quests.
- Costume: cosmetic identity and seasonal collection value.

Fairness rules:

- Every hero should have at least one deterministic unlock path.
- Random shard drops should fill progress meters.
- Duplicate shards should convert into useful, capped upgrade resources.

## 6. Economy And Resources

### Core Currencies

- Coins: common building and upgrade currency.
- Materials: district-specific restoration resources.
- Hero energy: fuels hero-slot sessions.
- Raid tickets: start raid or boss attempts.
- Shields: protect kingdom structures.
- Wild sparks: flexible event currency.
- Gems: premium convenience currency, never redeemable externally.

### Economy Principles

- The wheel should provide frequent small wins and occasional large in-game spikes.
- Hero slots should produce power, not just coins, so players feel progression variety.
- Poker raids should have bounded downside and clear consolation rewards.
- The builder should absorb excess coins and materials without blocking all progress behind rare drops.
- Premium currency can accelerate, refresh, or personalize, but not replace the core loop.

### Reward Cadence

- Every action: small reward, meter progress, or hero charge.
- Every session: at least one visible upgrade or collection step.
- Every day: meaningful daily wheel bonus, guild gift, or event milestone.
- Every week: district completion, new hero shard unlock, or guild boss reward.

## 7. Social And Live Ops

### Asynchronous Rivalry

Social actions:

- Raid: attack a rival structure for limited loot.
- Revenge: target someone who raided you.
- Gift: send energy, shield fragments, or event sparks.
- Assist: help guildmates repair or defeat bosses.

Anti-frustration controls:

- Shields absorb the first incoming raids.
- Damaged structures remain functional but need repairs for full bonus value.
- Recently raided players get temporary protection.
- Revenge targets grant bonus rewards but do not enable endless harassment.

### Guilds

Guilds are casual-first and should not require heavy coordination.

MVP guild features:

- Simple guild chat with moderation/reporting support planned for production.

First event: Festival of Falling Stars.

Event actions:

- No paid entry into contests with chance-based prize value.
- No ads for real-money gambling or betting services.
- No targeting under-18 players.
- Use clear purchase language: "gems," "energy," "cosmetics," and "boosts," not "wagers," "cash," or "payouts."

## 10. First-Time User Experience

### Tutorial Beats

1. Player arrives at a damaged sky kingdom.
2. Guide character introduces the Wheel of Fortune as a magical repair ritual.
3. First spin grants coins and hero energy.
4. Player repairs a landmark building.
5. Ember Chef joins through a guaranteed shard unlock.
6. Player uses Ember's slot board to charge a flame skill.
7. Player enters a scripted raid against a harmless practice rival.
8. Poker hand appears; player keeps a pair and triggers Ember's flame bonus.
9. Player returns with loot, upgrades the kingdom, and sees the next district goal.
10. Event pass and social revenge unlock after the core relationship is understood.

### Tutorial Success Criteria

- No more than one new currency introduced per step.
- All chance outcomes point to visible progress.
- The first raid must be impossible to fail harshly.
- The player should end the tutorial with a repaired building, a hero, and a next-session goal.

## 11. Visual Direction

### Art

- Floating islands, glowing taverns, magical reels, oversized cards, cozy buildings.
- Characters should be chunky, expressive, and readable at mobile scale.
- Use warm golds, sky blues, coral accents, leafy greens, and twilight purples.
- Avoid realistic casino floors, cash imagery, poker-chip stacks that resemble money, or adult gambling ambience.

### UI

- Large reward reveals.
- Simple meters for hero charge, district completion, event progress, and pity/progress guarantees.
- Clear icon language for coins, materials, energy, tickets, shields, and sparks.
- One primary call-to-action per screen.
- Event goals visible but not overwhelming.

## 12. Prototype Acceptance Tests

### Core-Loop Test

A new player should explain within 3 minutes:

- The wheel gives broad rewards.
- Slots power heroes.
- Poker resolves raids.
- Heroes and buildings improve future rewards.

### Differentiation Test

Target player reaction should be: "This feels like Coin Master with RPG heroes and tactical casino moments," not "This is just Coin Master with extra games."

### Audience Test

Casual puzzle players should understand what to tap next. Social-casino players should enjoy reward pacing, reel spectacle, and event milestones.

### Frustration Test

After being raided, a player should still have a clear recovery path: shield, repair, revenge, or guild help.

### Monetization Test

Paid options should accelerate progress or personalize play without implying real-world value, external prizes, or cash-out.

## 13. KPIs For Prototype Validation

- Tutorial completion rate.
- Day-1 retention.
- Actions per session.
- Percentage of players who use all three core chance systems.
- First raid completion rate.
- First building upgrade completion rate.
- Hero-slot repeat usage.
- Revenge participation rate.
- Guild join and gift participation.
- Purchases or ad watches by category, monitored for player sentiment.

## 14. Policy And Safety Notes

This concept should be reviewed by legal, platform policy, and age-rating experts before production.

Current official policy references checked while preparing this spec:

- Apple App Store Review Guidelines section 5.3 notes that gaming, gambling, and lotteries are highly regulated and that real-money gaming requires proper licensing, geographic restrictions, and other controls: https://developer.apple.com/app-store/review/guidelines/
- Google Play Real-Money Gambling, Games, and Contests policy allows licensed real-money gambling only under strict requirements and says apps with simulated gambling content should not display gambling ads: https://support.google.com/googleplay/android-developer/answer/9877032?hl=en

Fortunebound should therefore ship as entertainment-only social casino:

- Fictional in-game value only.
- No external redemption.
- No real-money gambling ads.
- No under-18 targeting.
- Clear terms, odds/probability disclosures where required, purchase transparency, and responsible play controls.

## 15. Open Decisions For Next Phase

- Final title and trademark clearance.
- Exact hero roster art direction.
- Initial economy tuning values.
- Age rating target by launch territory.
- Whether the first prototype should be playable or a clickable UX simulation.
- Whether to test the poker resolver before or after the hero-slot machine.
