Six days ago, an alien artifact the size of a city block appeared in our skies, directly over the planet's magnetic north. Since then, the Tesseract has been condensing, collapsing upon itself until it fits in the palm of your hand. Now, humanity's mission is to contain and control this mysterious object before its exponentially increasing destructive power erases us from existence, reconfiguring space-time for its extra-dimensional creators. Tesseract is a tense cooperative game for 1 to 4 players where dice manipulation is key. At the heart of the game is a block of 64 dice, the Tesseract, positioned at the center of the board. Players must remove these dice, bring them to their labs, transfer them among themselves, adjust their values, and crucially, isolate them in the containment matrix to neutralize them. To contain a die, you need to have three or more dice of the same value (a set) or in sequence (a run) in your lab, all of the same color or with no repeated colors. Completing the containment matrix with 24 unique dice ends the reaction and ensures victory. But beware: if the last die is removed before this, or if seven breaches occur, humanity loses and the world ceases to exist. Each character has asymmetric abilities, with a passive and a unique action. Research and containment cards, unlocked from the matrix, offer crucial advantages. The game is challenging, with high replayability stemming from the variety of characters and threat platforms that dictate difficulty. It scales well for different player counts, and the solo mode is equally engaging. Tension escalates quickly as the Tesseract releases and primes dice each turn, increasing the risk of breaches and bringing us closer to disaster.
