Take the T20 cricket format, and then just cut it in half. Each side bowls 10 overs, with each bowler allowed to bowl a maximum of two overs.
Powerplays are slightly longer proportionately with the first four overs, rather than six in T20, constituting a powerplay in which no more than two fielders are allowed outside the 30-yard circle."
