Super Times Pay Keno

Introduction

Super Times Pay Keno plays like ordinary four-card spot keno, except adds random multipliers. For the multiplier feature, the player must add 20% to his bet.

Rules

1. The player picks 2 to 8 numbers in the range of 1 to 80 on four different cards.
2. The player makes a bet that is evenly divisible by 5. 1/5 of the total bet shall be applied to each of four cards, for a total of 4/5 of the total amount bet. The other 1/5 is a fee to pay for the multiplier feature.
3. The game shall randomly determine if the player wins a multiplier.
4. If the player does win a multiplier, it can be 2x, 3x, 4x or 5x.
5. The game shall draw 20 numbers without replacement from balls numbered 1 to 80.
6. The base win shall be according to the number of balls that match the numbers chosen by the player. An example pay table is below.
7. If the player did not win a multiplier, then his actual win is the base win. If the player did win a multiplier, then his actual win is the product of the multiplier and the base win.

Example

In the image above I picked six numbers on each card. My bet was 10 credits per card, 8 of which went to the base bet and 2 to pay for the multiplier feature.

The game awarded a random multiplier of 3x.

On cards A and B, I caught 3 numbers for a base win of 3. Given by base bet of 8 credits and the multiplier of 3, the total win for that card was 8 × 3 × 3 = 72 for each card.

On card C, I caught 4 numbers for a base win of 4. Given by base bet of 8 credits and the multiplier of 4, the total win for that card was 8 × 4 × 3 = 96.

The total "win" for all four cards was 72+72+96 = 240. Keep in mind I bet 40 credits, so the actual win was 200.
