I think it was changed to a server-side script. It kinda sucks when a tiny bit of lag completely screws you over :/
Also, no one has really addressed the probabilities... Theres 2 green gralats, a bomb, an arrow, a heart, a couple blues, a couple reds, 1 yellow, 1 prize.
10/12 chance of losing between 20 to all 50 gralats.
1/12 chance of gaining 50 gralats
1/12 chance of getting the prize you want.
theres no "break-even" possibility, you just lose 83% of the time. Id even be okay if the probability of winning/losing gralats were a little more balanced.
