I have been working on the cascading mechanics for my match 3 game and have settled on a standard linear drop as opposed to a delayed, EASING\_INQUAD drop. Anyway, my issue is finding a balanced spawn system that does not generate so many of a single color instance. (Video attached)

My hope is there is a Match 3 pro among us that can assist a lowly dev. Right now I use a standard `math.random()`call. I googled and got an idea to use a buffered approach.

This would be a linear (or 2D) buffer of randomized tiles that are then run thru a `Fisher-Yates shuffle` and then each spawner plucks from the list upon request. The issue with this approach is my game has multiple spawners and some will use different spawned object list. I suppose I would have to create multiple list.

for example:

```lua
spawners =
	{
		{
			id = 0,
			{ spawn = "BLUE", probability = 1, board_max = 0, spawn_max = 0 },
			{ spawn = "GREEN", probability = 1, board_max = 0, spawn_max = 0 },
			{ spawn = "YELLOW", probability = 1, board_max = 0, spawn_max = 0 },
			{ spawn = "RED", probability = 1, board_max = 0, spawn_max = 0 }
		},
		{
			id = 1,
			{ spawn = "COIN", probability = 4, board_max = 0, spawn_max = 0 },
            { spawn = "BLUE", probability = 1, board_max = 0, spawn_max = 0 },
			{ spawn = "RED", probability = 1, board_max = 0, spawn_max = 0 }
		}
	}

```

Thanks for listening. Any advice would be greatly appreciated.
