pythrees is the clone of Threes!, which is $1+2=3$, $3+3=6$, $6+6=12$, and so on. If you have played 2048 game, you can find the similarity, both 4x4 grid, and merging with same numbered tiles, except the first merge of Threes!

The visual design is fairly simple, only a few colors and plain ASCII, but it does tell you what the next tile will be sliding in. It doesnt keep high scores.

Unintentional Christmas Tree is a fun and small arcade action puzzle game. You just lay the same color blocks on top of each other.

It has two modes, easy and hard. In hard mode, you cant make any mistakes, e.g. red on green, or that would be game over. In easy mode, lets just say that you can break this tree really easily.

The question is not red or green but left or right.
