I made a new puzzle game that you can play here. It is a variant of 2048 where there are tiles of two colours. You need to merge tiles of the same colour and value to increase your score. In more detail, the rules are as follows:
- You can shift all the tiles in one of the four directions (left, right, up or down). The tiles will slide until they hit the edge of the grid.
- if two tiles with the same value $v$ slide into each other then they will will merge into a single tile with value $2v$ and you will earn $2v$ points.
- After each move, a new tile will appear in a random empty location. The new tile will be either 2 or 3, chosen at random with equal probability.
- The game ends when all 16 tiles are on the board and there are no more moves to make them merge.
Here is a screenshot of the game:
I am yet to find a good strategy for this game. It seems that you cannot use the same strategy as in 2048 - build large values in one corner. This is because the second colour gets in the way. So I am wondering what is the highest score possible? The best I have achieved so far is 968.
