Proof! is a board game released in 2018 for 2–6 players, 10–20 minutes per game, and ages 9 and up. Its main mechanics are Pattern Recognition.
Nine cards, each with one number from 0 to 100, are arranged face-up in a 3X3 grid. Players simultaneously try to create equations using at least three cards in the grid and as many math symbols as necessary. A player keeps the cards he uses to make an equation, and those cards are replaced in the grid with new ones. Play continues until the deck runs out. The player who has collected the most cards wins.
Proof! supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Proof! is 10–20 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Proof! for ages 9 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Proof! has a complexity rating of 2.0 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
Proof! belongs to these categories: Card Game and Math. Its main mechanics are Pattern Recognition. Categories describe the theme and setting of a game, while mechanics describe what players actually do on their turns. Each mechanic links to a catalogue hub with similar games, which helps when you want something comparable.
The catalogue lists Proof! as a base game. It can be played on its own with the components in the box and does not require any other title. Expansions, if any exist, add new content or rules on top of it and are listed separately in the catalogue with a link back to this base game.
