I think it would be great to introduce a "Combo Challenge" feature where players complete a set number of challenges to earn varying prizes. For example, participants could be required to finish at least 3 out of 6 challenges to win a minimum prize, with bigger rewards for completing all six.
The challenges could include tasks like:
Plinko - 130x
Keno - 600x
Mines - 1077x
Limbo - 10,000x
Dice - 1980x
Hilo - 400x
This format encourages flexibility, as players can choose which challenges to complete while still being rewarded for their efforts. It also provides motivation to aim for completing all six challenges for maximum prizes.
