BrainBall Task 2.2
The goal of this game is to reduce the board of tiles so that only one tile remains. Sometimes this is difficult or even impossible but try to leave as few pieces as you can.
Eliminate the pieces by dragging tiles onto one another. You may only combine tiles that have consecutive numbers, for instance a 2 may be moved onto a 3 or onto a 1, but not onto a 2 or a 4. Additionally, pieces must be vertically, horizontally, or diagonally adjacent to one another.
The round will end automatically if you manage to reduce it to one tile; otherwise, click the “I’m done” button when you can reduce the board no further.
