User reviews

Iโ€™m deleting this one

1) It has ads. Many ads.
2)Some of the colors are indistinguishable. Actual user testing would have made this obvious.

Fun Game, Many Ads

There are way too many ads. For every level you play, you have to watch multiple ads. Waste of time.

Way too many ads!

This is a fun game, but you literally cannot get through even one level without watching at least two ads. Itโ€™s ridiculous! Iโ€™m looking for a different app.

Stupid

Why are there five empty slots when you can only use 4? Why does the game end when you put a screw in the fifth spot even though you can keep playing?

Not like advertised

Says no ads but there are and game doesnโ€™t look like itโ€™s advertised either
