Tap to stack blocks and build a tower. Misplace a block and your tower shrinks, but perfect landings restore its width. Master three distinct modes with increasing challenges and strategic pickups.
What's New in Plumb
1.1
September 21, 2026
Sound! Every drop, trim, and perfect landing now has its own sound — mute it anytime from the new Settings screen. Near misses now get called out — a drop that just grazes the perfect window gets its own "SO CLOSE" instead of looking like an ordinary miss. How to Play now shows real gameplay for whichever mode you've got selected, not a wall of text. Colorblind-friendly colors in Arcade and Gravity, plus support for VoiceOver, larger text sizes, and Reduce Motion. A new Settings screen: mute sound or haptics independently, and restore a purchase without digging through the game-over screen.
