Stack Builder is a one-tap precision stacking game. Tap to drop the moving block onto your tower - land it clean for a perfect stack, or clip the edge and watch it shrink. How high can you go before you miss?
- Solo Mode: stack as high as you can, beat your own best height
- AI Battle: race an AI opponent to 100 - first to the target height wins, or highest score after 60 seconds
- Three AI difficulty levels: Easy, Normal, Hard
- Perfect-landing streaks trigger combo effects and confetti
- Expressive block characters that react as you play
- Offline-friendly, no login required, no account needed
- Occasional house cross-promo cards (no third-party ad SDK)
