Stack unblocked is a precision-based challenge that traps you in a rhythm of perfect timing and focus. You watch moving blocks slide across the screen and tap to drop them onto your growing tower. If you miss the edge, the overhanging piece slices off, shrinking your platform and making the next placement harder to judge. You stack as high as possible while the blocks move faster, requiring steady hands to maintain your base. It is simple to pick up, but the game demands total concentration to reach a high score.

How to Play & Controls
- Left Mouse Button / Tap Screen: Drop the current block onto the tower with a clean click.
Tips & Tricks
- Watch the corners of the block instead of the center to time your taps perfectly.
- Aim to align the blocks with the one underneath to keep your platform at maximum width.
- Wait for the block to reach the center of your stack before tapping to minimize the margin for error.
- Ignore the flashing lights and stay focused on the block edges to avoid making a mistake under pressure.
