For the first match, characters are chosen double-blind - at the same time, so that neither player knows his opponent's character beforehand. In practice, this rule is often ignored, but players always reserve the option to force a double-blind pick
The loser of the first match (and of successive matches) chooses the next stage, and then the winner chooses his character, and then the loser chooses his character. This series of choices is called slob picks.'
The loser can pick any stage except for the following, and possibly more, depends on tournament.
* Brinstar Depths
* Flat Zone
* Fourside
* Great Bay
* Icicle Mountain
* Temple
* Yoshi's Island (N64)
The above stages are banned.
No stage can be chosen twice.
Some tournaments allow the winner of the match to ban a stage from play- it gets "striked" and therefore, even if chosen on random, cannot be played.
