Glitch puts two near-identical pixel pictures side by side and corrupts a handful of cells in one of them. Your job is to find every change before the buzzer.

Wrong taps cost you and five misses short the board out entirely, so it isn't a game you can brute-force by tapping everything. It's a speed race with a real penalty for carelessness.

How to play Glitch

  1. The host picks the round count

    Six rounds is the default at 40 seconds each.

  2. Two pictures appear

    The original on one side, the corrupted copy on the other. A few cells differ.

  3. Tap every glitch you find

    Taps register immediately, so you know at once whether you were right.

  4. Wrong taps cost you

    Five misses short the board out and end your round early — accuracy matters as much as speed.

  5. Clear the board for a bonus

    Find them all and the faster you swept, the bigger the bonus on top.

What Glitch looks like

Two near-identical pictures. Tap every change before the buzzer — and wrong taps cost you.

How scoring works

Each glitch you find banks points. Wrong taps subtract, which is what stops the winning strategy from being a rapid tap across the whole grid.

Finding every glitch earns a clean-sweep bonus scaled by how quickly you did it, so a fast full clear is worth far more than a slow one.

Five wrong taps ends your round early with whatever you'd banked. Points accumulate across rounds.

Tips for winning Glitch

  • Scan in a fixed pattern — rows or columns — rather than letting your eye wander. Wandering is how you tap the same wrong cell twice.
  • Look for colour changes before shape changes. A recoloured cell pops out much faster than a removed one.
  • Missing cells are the hardest glitch. If a picture has an obvious gap, check whether the original had something there.
  • Slow down after three finds. The last glitch is usually the one that costs people their sweep bonus.
