Cubb - 2x2x2 cube

Mini Cube (2x2x2) app, including :- Animated 3d cube- Smooth touch intece (can lock whole cube rotation)- 4 Skins to chose from.- Tutor mode. For every possible cube : ---+ Shows solving algorithm ---+ Lists algorithm moves---+ Shows next move using arrows---+ Fast-forward to next algo whenever you want to- Stats : keep track of your solving times.- World wide leaderboard. Are you the fastest ? faster than your friends ?- Achievements - Scramble (unbiased)- Optimal solver : explore shortest sequences for solving any position.- Move log : navigate in your move history, and replay previous scramble.FAQ :HOW DO I ROTATE THE WHOLE CUBE ?- drag between two slices- drag outside the cube (left/right or up/down. No clockwise rotation this way)I'M FOLLOWING ARROWS IN SOLVER, TO NO AVAIL.After solving the first layer, you have to turn the cube upside down using either a center drag, or by two parallel half-turn slice moves. I assume that you're stuck there (the next move arrow is in the middle, but it's not that obvious). Using green bottom right arrow should works too.
