Two teams of players, fielders vs batters. Playing with four bases batters must try and get around without being bowled, caught or run out by the fielding side. Every time they succeed and pass the forth base they score a point for their team.
You can limit how long this games lasts by imposing a time limit for the batting side before they must rotate or a set number of innings.
Normal rounders rules apply, so if players are between bases they can be stumped out and there is a limit of one player per base.
