About the game

What you do in a play session

Inside the eccentric laboratory of Dr. Barabara, numbers never stay the same. Each card can be broken down into smaller parts, giving players endless ways to combine them. A 6 might become two 3s, three 2s, or even a 1‑2‑3 sequence, and every choice changes the flow of the game. The goal is to climb a numeric ladder, reaching the top before your opponents. When a player throws a prime number, the field can reset, opening doors for surprising comebacks. The game is set for 2 to 6 players, lasts 15 to 30 minutes, and sits at a low‑to‑medium complexity level—perfect for groups looking for something quick yet engaging. The components are simple: a deck of numbered cards and a discard pile. The Ladder Climbing mechanic makes each turn decisive, while the decomposition option keeps the play unpredictable. If you enjoy games that blend luck, planning, and a dash of number science, this title will delight you. Get ready for laughs, competition, and the chance to earn the title of “Genius” in the lab. The standard deck contains cards numbered 1 through 10, each of which can be used flexibly. On a turn, a player may play one or more cards onto the discard pile, provided the total is equal to or greater than the last card played. If they cannot, they must draw cards. The twist is that before playing, the player can choose to decompose a card into smaller combinations, as long as the total sum remains the same. This allows for “prime cut” plays, where a prime number can become a turning point, clearing the pile and forcing opponents to rethink their strategies. The ladder dynamic requires players to keep an eye on the top, because the first to reach it wins. The game ends when a player runs out of cards. If all players still have cards, the game continues until someone climbs the ladder. The pace is brisk, with each round lasting only a few seconds, and decisions are rapid, keeping everyone engaged. The artwork is minimalist, with bright colors and clear numbers for quick reading. For fans of card games with a math twist, this title offers a light, fun experience with room for creative strategies using number decomposition.
