  We study the problem of optimal games for the solo and coop modes of the
board game Room 25 (season 1). We show that the game cannot be won in a single
turn for any starting configuration, but that it can be done in two for some
configurations. We introduce an opening that wins in two turns with enough
luck, while having a low probability of losing immediately. We then show that
the game can be won in a single turn if the game's rules are slightly modified,
although the probability of winning then becomes substantially lower than in
the two-turn strategy. At last, we show that if the players are maximally
unlucky, they will lose regardless of their strategy.
