RotoDots: free puzle app for iphone, ipad

RotoDots is a dexterity puzzle app.  The black line rotates and you must tap the screen when it passes over the pink dot.  When that happens, the big central circle changes colors and then you have to stop the dial on whatever color matches it.

This game is way too hard for me.  It's a great concept, but the speed is too fast.

This game definitely gets its inspiration from Pop the Lock, which is simple but brilliant.  Winter Color Spin is another variation. Links below.

RotoDots is free.
