Choose an edge. Then explore.

Every move sends the entire tray towards one edge. Equal values that meet combine once, then a new 2 arrives in an empty plot. Space is your most useful ingredient.

1. Choose an edge

   Use the four direction buttons. On a keyboard, focus the tray before using arrow keys so the rest of the page remains scrollable.

2. Join equals once

   Values slide as far as possible. Matching neighbours combine once per move, adding the new value to your score.

3. Protect an empty plot

   A changed board receives one new 2. A direction that cannot change the tray adds nothing and does not use the undo state.

4. Undo or plant again

   Undo slide restores the last changed tray and score once. Fresh tray starts with two small sweets and clears the previous result.
