How high can you stack? ZapStack is a one-tap precision platformer where every landing counts. Platforms swing back and forth — tap to jump through the gap and lock them into your tower. Land dead center and the gap stays wide. Drift off-center and it shrinks. The further you go, the less room for error. Simple to pick up. Hard to put down. HOW TO PLAY - Tap anywhere to jump - Time your jump to fly through the gap in each swinging platform - Each locked platform adds to your tower - Hit dead center for a Perfect — keep the gap at full width - Land off-center and the gap narrows - Miss the gap entirely and it's game over PRECISION MATTERS Every millimeter of drift costs you. A perfect run keeps the gap wide open. A sloppy run turns it into a needle's eye. Your skill is written into every platform you stack. THEMES Play in the bright Daytime world or hop into the Easter Bunny theme — basket weave platforms, a bunny player, and spring meadow skies. More themes arrive automatically, no app update needed. COMPETE Climb the Game Center leaderboard. Beat your personal best. Share your best tower with friends. ZapStack is free to play with no ads and no paywalls. Just you, your reflexes, and a growing tower.

Verdict

The call

Scrap Divers's advantage is ratings volume (1.3K vs 1). On price, review sentiment, device support and iOS requirement there is nothing between them.
