Doublings

INSTRUCTIONS

Click on any blank square to drop your tile there. Put two of the same number next to each other to combine them. If you drop next to a different number, it will kick that number away. Keep doubling your numbers to get a new high score!

When you combine three of the same number at once, you earn a bonus tile in the bottom row. You can swap the number you are holding with any of the numbers in the bonus row by clicking on it.
