Editors’ Notes

Is it a silhouette of two faces, or is it a picture of a vase? In the spirit of that classic optical illusion, Voi is an elegant shape-matching puzzler that makes you think about what isn’t there as much as what is. An accessible, zen-like experience with no time limits and no pressure, it’s simultaneously challenging and calming.

Simple yet challenging

The concept is simple, a bit like tanagrams except the pieces can overlap -- which changes the overlapped areas from black to white or vice versa (against a white background). Very intriguing, and some of the puzzles are quite challenging. It's different from other games and that it itself makes it enjoyable to play. Watching the designs you create as you try to duplicate the shape given is lots of fun too.

I would agree with others that it would be helpful for the completed shape to hold its form for three or four seconds, rather than instantly dissolving.

Another mind-bending puzzler

It's hard not to compare this game with Zengrams; voi is similar in concept and similarly satisfying (though not quite as challenging overall). Like Zengrams, there are no in-app hints or level skips, so there is the possibility of getting stuck. However, the number of moves is not limited and the pieces never "fuse," so you're free to fiddle around as long as it takes to find the solution. There are some cleverly designed puzzles here, but nothing quite a devious as the best of Zengrams'. Some toward the end were disappointingly easy. Looking forward to more in future updates.
