About This Game

Do you think 1 + 1 = 0 is correct? So what do you think about "black + black = white" statement?

VOI is relaxing minimal puzzle game based on XOR logic;

0+0=0
1+0=1
0+1=1
1+1=0

VOI gives you a few draggable geometric shapes (triangle, square, rhombus, parallelogram etc.) to reach target shape. That's all. Do you think that the easy?

* One page game (no start button, no exit button)
* Cool music and fx
* Use mouse wheel to scroll levels
