About pattern
pattern is a free color gradient puzzle you play in the browser. Each round shows a grid of tiles that fade smoothly from one color to another, except for a few pairs of tiles that have been swapped out of place.
Find a tile that breaks the gradient and drag it onto the tile that belongs there. The two swap, and when every tile is home the board is solved. The faster you solve it, the more the round is worth.
A run is five boards worth up to 10 points each, 50 in all, and each board hides more swapped pairs than the last. Pick easy or hard, and play the daily set, five boards that are the same for every player that UTC day.
