7x7

7x7 is a puzzle game for Android. The game is noted for following the Android design guidelines, something most Android games do not attempt.

The playing field is a seven-by-seven grid. Players move colored blocks to match four in a row, and remove the blocks from the playing field. Gameplay is turn-based with no timer. After each move more blocks are randomly added to the grid. The game ends when the grid has been filled with blocks and no more moves are possible.

The ability to move a block anywhere is awarded by clearing multiple rows in a single move. The ability to undo the last move is awarded after each level is cleared. Two of each of these are available at the start of each game.

The game supports achievements and leaderboards through Google Play game services.
