How to Play Obby Stacker
Obby Stacker is a simple but addictive one-button timing game. A block slides back and forth above the tower — press Space to drop it. Every miss shaves the tower a little thinner, and the challenge is to see how tall you can build before it all comes tumbling down.
Time Your Drop
Wait until the moving block lines up perfectly with the one below it, then press Space. A perfect drop keeps the tower at full width.
Every Miss Costs You
An off-center drop slices off the overhanging edge. Miss too many times and your blocks get too thin to stack on.
Chase the Perfect Stack
Perfectly aligned drops can even restore width and earn bonus points. Aim for a flawless tower.
Beat Your Best Height
Your tallest tower is saved locally. Each run is a chance to set a new personal record.
