That's prettymuch it Obsi!
The number of players depends on how you want to play, 1v1, teams (2v2 or more) or an all on all kind of mayhem.
Intentional contact isn't allowed, your just really aiming to make them fall and be the last one standing.
Placing blocks is illegal also and anyone knocked out can't intefere with the on-going game.
If more than one player is left but they cannot reach each other to continue play, the player with the most blocks around them is the winner.
There are alot of variations;
- No jumping, where the ceiling is limited and players can't jump across the holes that are made.
- Multiple layers that get harder or easier as you progress down the levels/surface. Most rules also allow the players that fall through to still destroy the blocks above them.
- Mazes, built onto the surface with wide lanes and places to loop back around.
There's also alot of house-rules and some other craziness like playing in the dark and lighting the surface on fire.
I like your idea with the different colours, the pattern would have to be quite random but also quite evenly spread to be fair on all. That would be fun for a team event.
For things like the maze, different levels and some of the more destruction orientated ones we'd have to build another arena, but it wouldn't be hard to knock something up if even only temporary.
Starting the sheep farm is a good idea as theres also another project I'd like to try out in the same "fun park" area that would require some.
