Remove pairs of equal numbers or numbers that add up to 10 until the changing board is completely clear.
Guía interactiva
Find pairs, open gaps and use those gaps to create new connections until the board is empty.
Tap two equal numbers or two numbers that add up to 10, such as 3 and 7 or 6 and 4.
The pair must align horizontally, vertically or diagonally through gaps, or be consecutive in reading order. On mobile the board may be shown rotated, but the game and its connections stay the same.
Matched numbers disappear without collapsing the grid. The empty spaces can connect numbers that were previously blocked.
If no valid pair remains, append the remaining numbers in the same order and continue until the board is clear.
