SynotTip

In SynotTip's Stack, the sliding block doesn't maintain a constant pace, it accelerates as you climb higher, compressing the timing window for each tap and raising the difficulty as the tower grows. Early layers give you plenty of time to judge the block's position and tap confidently; by the upper layers, the block sweeps across the tower top so quickly that the margin for a PERFECT shrinks to a fraction of a second. This speed increase ties directly to the trimming mechanic: faster block movement means misalignments are more likely, and a narrow stack combined with a fast block is the game's hardest state to recover from. The BONUS block every ten layers provides a speed-independent reset: even at high speeds, landing on the BONUS restores width and gives you a fighting chance to push higher. Stack runs at 60fps to keep the sliding animation smooth and timing feedback precise, all stored locally with no account needed.
