I think the best technique is to think of a number between 10 and 33 then write in advance your selection i.e. 1=Circle or Red 2=Star or Blue 3=Star or Blue 4=Green or waves etc, when inputting your selections don't look at your stats until the end.
I think challenge matches could also take place, between those who think they can beat someones score i.e. best of 100 goes, highest score wins.
Could also set up a knockout series, 32 players register, then play off until a winner is produced.
I think this is mentally a relaxing game, also quite catchy, once you have logged a score, you want to try and beat your last stats.
