After entering a level, the level number and countdown timer are displayed at the top. You must eliminate all blocks within the time limit.
Tap two blocks with exactly matching patterns to pair and remove them. Paired blocks will disappear.
Matching slots are reserved at the bottom of the screen with a maximum capacity. Difficulty spikes if slots fill up and no valid matches can be made.
Clear all blocks to complete the level successfully. If the countdown hits zero with leftover blocks, you trigger Game Over with the prompt: Blocks Out of Order.
Level progression: No.1 → No.3 → No.5 → No.7. Later levels feature more blocks on the board and tighter time limits.
Unstable: Block Drift is a cyberpunk sci-fi match puzzle mobile game.
