There are 13 Achievements to earn as well. (there are unlimited moves and time in the Bonus Game) Completing Level 20 gives you the Key to unlock the next Pyramid. The tiles don't regenerate so you have to use strategy to and anticipate the pattern of the falling tiles. Halfway through the levels, you get to play a really creative three-part Match 3 Bonus game where you must remove all tiles. There are 4 Pyramid locations and each Pyramid has 20 Match 3 Levels which can be replayed as often as you'd like. There is, however, an Expert Mode of difficulty which is maddeningly challenging, and incorporates both Limited Moves AND Limited Time! There is also a Relaxed Mode (unlimited time and moves) and a Casual Mode of difficulty with Limited Moves, but you won't earn Stars in either of those modes. VERY CHALLENGING MATCH 3 If this game had an option for playing in a Timed Mode only, I would have immediately purchased it, but I rarely enjoy a Limited Moves Match 3 game.
