About Stack Sprint
Stack Sprint is a compact construction challenge driven by a single decision: when to drop. Every new block travels from side to side above the tower. The part that misses the floor below is removed, making each imperfect placement permanently narrow the structure.
How to play
Drop the moving block while it overlaps the top floor. A successful placement adds one point and creates the base for the next block. Missing the tower completely ends the run.
Tips
Track the leading edge rather than the center when the tower becomes narrow. Letting a block make one extra pass is safer than reacting before you understand its speed.
