LUM PATTERN

How to play

1. Look at the fixed edge columns: they set the gradient.
2. Tap two tiles, or drag one onto another, to swap them.
3. Repair everything before the clock. A round with no extra swaps is perfect.

Color changes gradually across the board and from top to bottom. The edge columns stay fixed. Find tiles that interrupt the gradient and swap two with a click, tap or drag. Any two movable tiles can be swapped.

Keyboard: arrows to move through tiles; Enter or Space to select; Escape to cancel selection. P pauses practice. In timed challenges, help and background tabs do not stop the clock.

LUM coins

You earn coins at the end of every session (score, perfect rounds and five out of five), from the daily reward and from three daily missions. Signed in, the server rebuilds your game from its seed to compute them and saves them to your account. They cannot be bought with real money.

Daily challenge

Five identical boards for everyone on each UTC day, always on Easy. One official attempt in this browser: starting consumes it even if you leave early.

Same challenge, clear rules

Seeded patterns, reversible initial swaps and distinct colors. Randomness stays fixed during a round and never adapts to your results or purchases: tables only change the material, never the colors. In duels, lower total time breaks a score tie; equal times mean a tie.

Each round is worth up to 100 points based on time remaining. No hidden swap penalty.
