Tresling = Tetris + Arm Wrestling

Tresling is the combination of one of the most beloved video games ever made, Tetris, and one of the fiercest sports around, arm wrestling. The idea is that you move your arm to move your piece and tap a button to rotate it, however, you do that while locking arms with an opponent. So, the loser not only sucks at Tetris, but he/she also is physically weak.
