Match-3 Board Systems
01The core board loop depends on predictable swap validation, match detection, cascades, refills, and feedback timing.
- Swap validation
- Match resolver
- Cascade handling
- Board refill
Boosters and Rewards
02Boosters turn board events into satisfying power moments while feeding rewards and economy progression.
- Booster charge
- Reward events
- Daily goals
- Leaderboard payouts
PVP and Live Modes
03The same board resolver can support free play, story goals, tournaments, PVP scoring, and prize modes.
- PVP flow
- Tournament scoring
- Mode contracts
- Live event hooks
Match-3 Session Architecture
Board actions resolve into cascades, rewards, leaderboard events, and economy updates through clean gameplay contracts.

Lessons Learned
Match-three projects stay maintainable when board logic is separated from mode and reward logic.
Boosters should be treated as gameplay events, not one-off visual scripts.
PVP and Web3 layers need stable gameplay event contracts to avoid fragile integrations.
