About the game

What you do in a play session

Get ready for a mental challenge in Solver, a game that turns your table into a giant collective puzzle! One player takes on the role of the Master and secretly creates a unique rule using a special deck of 64 cards. These cards combine numbers, shapes, and colors, opening up a vast array of possibilities. The other players, the Investigators, must use all their logic, creativity, and observation skills to uncover this mysterious rule before anyone else. Each round, a trail of cards forms: those that follow the rule go into the main sequence, while those that break it go into an error trail. On their turn, an Investigator plays a card and decides whether to risk a guess about the rule, draw a new card, or exchange their entire hand (once per game). The game ends when someone correctly identifies the rule or when the 25th card is played. Solver offers three game modes to suit everyone: Casual, for those who enjoy a lighter, more creative experience without worrying about scoring; Competitive, for strategists who want to test their skills and accumulate points; and Cooperative, where everyone works together against the clock to decipher the enigma. With quick 10-20 minute rounds, it's perfect for kicking off game night or for that strategic break. If you enjoy deduction games, pattern recognition, and a good mental challenge, Solver is for you!
