Ive seen this in other games where they have:
Slot machines:use our gold(the pictures on them can be bird bears mages )
Playing cardsoker (this may be a little mature since this games for younger players to)
Word searches:
Scrabble:
Mazes:

Sport mini gamess
Bowling:
Tennis:
Pool:
Etc...

Idk i really like the gambling ones though like slotmachines and poker..cause you can gamble on winning gold(just another way of gainin gold in pl)!
