why not use the hats to make a percent challenge. Eg win 50k in gold while having 36% of muliplier buff hats on - so the player must configure hats to total 36% and then win the gold - with options like that, challenges would be endless, and we can have more challenge monkeys - imagine a challenge with all 1% hats - many would be in trouble because they sell there 1% hats - it would make the game interesting again
