4K* - Treasure Chest bonus round for MAX Bet 4 of a Kind. Possible payouts: 140, 180, 250, 500 or 5000 Credits
The Treasure Chest routine works as follows:
1. The chest picked is used for animation purposes only. The chest DOES NOT determine the payout.
2. A call is made to the random number generator for a number between 0 and 399 (400 possibilities)
3. The number generated is used through a look up table to determine the bonus prize:
Number Generated Award Odds Chance
