Looking over the rules, it looks like there's an assumed "causal"-ness to the game (not good, not bad, just noting there's an assumption that everyone will play by the rules at all times). Based on the rules [1], there doesn't seem to be any consequence to fouling if you do not have the ball. What stops a non-carrying team player from stepping in the center or tackling a player?<p>Given the current ruleset, nothing. Three fouls give you a demerit, three demerits give you a reprimand, 3 reprimands ... to infinity. Secondly, is there a difference in severity to stepping in the center vs. tackling?<p>I get that you could say that 2 fouls is a timeout, and certain rules carry higher penalties (1 for center stepping, 2 for tackling), but it is not written.<p>[1] <a href="https://playspeedgate.org/8/" rel="nofollow">https://playspeedgate.org/8/</a>
