as it stands, mini games don't offer much in challenge or rewards, you get a handful of mgp if you do well, and no bonuses for "chaining" high scores together. Mayhaps add achievements for chaining highest scores together?

ex. Get a toy hammer minion for getting 50 perfects in a row on crystal tower game? or add mgp multiplier for 10x, 20x, 50x, 100x perfects in a row?
