# Decatron

## Introduction

Decatron is a simple "instant" game by Funfair Technologies. There is one bet only, which pays according to the poker value of a random number between 0 and 99999.

## Rules

1. After placing a bet, the game will choose five numbers, with replacement, from 0 to 9.
2. The player is paid according the poker value of said five-digit number, as follows:
• Sequential high straight — 1000 for 1
• Five of a kind — 100 for 1
• High straight — 50 for 1
• Four of a kind — 30 for 1
• Straight — 15 for 1
• Full house — 10 for 1
• Three of a kind — 5 for 1
• Two pair — 2 for 1
3. A "sequential high straight" is 5-6-7-8-9 in that order. The reverse order does not count.
4. A "high straight" is 5-6-7-8-9 in any order (except sequential)
