## Description

### Hanafuda Koi-koi Collection

Hanafuda Koi-koi Collection brings the classic two-player Japanese card game Koikoi to your browser with real 3D visuals. Play against a CPU or another player, matching cards by month and plant to claim them and build yaku (scoring hands). The game emphasizes strategy and timing, letting you enjoy authentic Koikoi gameplay in a modern Chrome extension.

Gameplay revolves around a LIFE system: you start with 25 LIFE points; every time you cut a card costs 1 LIFE. When you win a yaku, LIFE increases by the yaku's value; if the CPU wins, LIFE decreases by that value. There is no limit to the number of rounds—play continues until LIFE runs out, while you compete for the total yaku points earned.

## Review summary

Overall, players praise the core koi-koi mechanics and accessibility, plus a fast pace. However, widespread concerns about the AI/RNG, a rigged scoring system, and heavy ads undermine the experience. Some appreciate offline ad-free play and the visual vibe, while others want more modes and customization to improve balance and longevity.

### Pros

- English localization makes the game accessible to English-speaking players.
- Fun and engaging gameplay that can be won with attention to the cards, despite luck.
- Fast loading times and quick rounds provide a smooth, snappy experience.
- Offline play (ad-free) option is available if ads are removed.

### Cons

- Pervasive ads and irritations from advertising.
- Unbalanced AI with frequent lucky draws/RNG making the CPU seem to cheat.
- Rigged or restrictive scoring system that limits repeated plays.
- Desire for more game modes and customization; lack of variety.
