1. Only 1's or 2's can be tapped.
2. They can be tapped if and only if there are 2 identical numbers adjacent to it.
3. Two 2's will merge to form a single 3 in the space between them.
The first tap will automatically lead to a massive chain reaction.
Coming up with a strategy is tougher than I thought.
My high score is 1164 and my highest tile is 8.
numDance definitely has an addictive element because you can play one game in about 5 minutes.
If you manage to get a 9 tile, take a screen shot and post it in the comments section.
