Make 5

Drag and drop numbered blocks to merge them to make larger number blocks. See how long you can survive before the board fills up.

Drag and drop the numbered blocks at the bottom of the screen onto the board.  3 or more same type of number blocks next to each other will automatically combine together into a larger number block.  Combine 3 or more a "5" blocks and they will disappear taking out nearby blocks too.  You can rotate pairs of blocks before placing them.
