Rules of the table

Seven by seven, under the dome.

Swap
Pick a tile, then a neighbour. With a keyboard, use the arrow keys and Enter or Space.
Match
Three alike clear. Four in a row leaves a sweep tile that clears its whole row or column. An L or T leaves a flare. Five alike leaves a star ring that clears every tile of one kind.
Clouds & crates
Clouds lift when you match the tile under them. Crates open after two nearby matches.
Tools
One pick, one wind and one flare per sitting. Each costs nothing and never runs a timer.
Moves
When the moves run out you get five more, once. After that, sit again for free.
