Do powerups need to be used immediately?

The Sonar and Scanner powerups can be banked and used at any point. The ricochet powerup must be used in the next 5 shots after getting it.

How does ricochet work?

Ricochet can be called when firing a shot in the next 5 shots after getting the powerup. When it is called, a RANDOM tile surrounding the hit tile will be selected to be auto-completed. There must be at least 3 options for the random tile to choose from.

Do we have to call our shots as soon as we get the drop?

Preferably, yes.

Do we need to tell the other team when they have sunk a ship?

Yes.

Can each team get the powerups from the tile they are secretly placed on?

No, once a powerup has been claimed the other team may not also get it.
