Number Merge

A match 3 game where you modify the number tiles on the board by dropping '-1', '1' or '2' tiles from your list to create new numbers. The '-1' tile subtracts one from the number it is dropped on while your '1' and '2' tiles add one and two to the number tile it is dropped on. Strategically drop the number tiles from your list of tiles to make matches and keep your list topped up.
