Just Stack
Read full descriptionHide full description
How high can you stack? Just Stack is a one-touch arcade game about timing, nerve, and precision. A block slides across the screen. Tap to drop it. Every imperfect landing trims your stack smaller. Miss completely and the run is over. Easy to start. Hard to master. **STACK WITH PRECISION** Land each block cleanly to keep your tower alive. Hit perfect drops to build combos and push your score higher. **STAY CALM UNDER PRESSURE** Wait too long and the active block starts shrinking. Make your move before it disappears completely. **USE STARS WISELY** Collect stars during a run and spend them on WIDE, a boost that restores full width for your next drop when you need a second chance. **WATCH FOR HAZARDS** Bombs start appearing as your score climbs. Tap them before they hit your block, or risk losing part of your stack. **CLIMB THE LEADERBOARDS** Track your best run, compare scores, and compete through Game Center. **JUST ONE MORE GO** Just Stack is built for quick sessions, instant restarts, and that constant feeling of one more try.
