Take a Spin

The two programs are three reel slot simulators, each with ten symbols:

0: BAR
1: Cherry
2: Orange
3: Plum
4: Bell
5: Lemon
6: Watermelon
7: Seven
8: Apple
9: Shamrock

Slots Version 1: Classic Adapted Version

This version is adapted from the HP-19C/HP-29C Games Solutions: Games book, which in turn, the original program was adapted from HP-65 user program by Craig A. Pearce.

Each spin has an ante of 10¢. The results appear in the form 0.### (ignore the left most 0.)

The payouts are these:

Cherry on the first slot, 0.1xy: 20¢
Cherry on the first two slots 0.11x: 30¢
Three of a kind other than cherries, 0.xxx where x≥2: $1.00
Non-cherry symbol on the first two slots, BAR on the third, 0.xx0 where x≥2: $1.00
Three BARS, 0.000: $10.00

To operate:

1. Initialize: XEQ S
2. Spin: XEQ J
3. Check your winnings or losses: XEQ K
