  Inspired by asynchronous cooperative Parrondo's games we introduce two new
types of games in which all players simultaneously play game A or game B or a
combination of these two games. These two types of games differ in the way a
combination of games A and B is played. In the first type of synchronous games,
all players simultaneously play the same game (either A or B), while in the
second type players simultaneously play the game of their choice, i.e. A or B.
We show that for these games, as in the case of asynchronous games, occurrence
of the paradox depends on the number of players. An analytical result and an
algorithm are derived for the probability distribution of these games.
