To choose one out of three, either reverse this (the odd coin out is the winner), or add a regular two-way coin flip between the remaining players as a second step. To choose two out of three, three coins are flipped, and if two coins come up the same and one different, the different one loses (is out), leaving two players.

The coin remains at a constant inclination to the vertical and simply rotates, or wobbles, about a vertical axis.

If the outcome is unclear the toss is repeated for example the coin may come to rest upright against another object or fall down a drain. When the coin comes to rest, the toss is complete and the party who called or was assigned the face-up side is declared the winner. Depending on custom, the coin may be caught, caught and inverted, or allowed to land on the ground. The other party is assigned the opposite side. Either beforehand or when the coin is in the air, an interested party calls "heads" or "tails", indicating which side of the coin that party is choosing.
