SABTC
Simply A Box That Changes
Free · Designed for iPad. Not verified for macOS.
Every tap changes the board. Every chain changes your score. You have 12 moves. Think ahead and master SABTC.
A minimalist puzzle game where every tap changes the board.
Tap a box to advance it. When enough neighbouring boxes line up, they change together, creating chains that can keep the board moving. The longer your chain, the bigger your score.
You have 12 moves. Every move matters.
THINK AHEAD.
