This is simply to test how each valid input appears. For all candies that spawn, put a number from 1 to 8.
For some candies that don't spawn, put two numbers, the first being less than the second.
For example, putting 56 results in 5 to 6 colors, which means five colors spawn, but a sixth color appears, whether on the starting board or through spawners or dispensers.
For another example, 18 results in 1 to 8 colors, with one only spawning naturally, the other seven spawning through other means.
