Here's the rules. Listen up.
Use your inventory in the bottom left corner of your screen to bet. Once you place a bet you can roll the dice.
If you roll 4-5-6, you automatically win.
Rolling three of the same number is known as rolling "trips". Higher trips beat lower trips, so 4-4-4 is better than 3-3-3.
If you roll a pair and another number, the pairs cancel out and only the remaining point counts. A higher point beats a lower point, so 2-2-6 is better than 5-5-2.
If you roll 1-2-3, you automatically lose.
Drain your opponents cash supply to move on to the next level.
