Tesseract

Tesseract is a cooperative dice-manipulation puzzle centered on a striking four-by-four-by-four structure of sixty-four dice. The alien artifact destabilizes after every turn, shedding cubes, revealing event symbols, and threatening catastrophic breaches. Scientists spend action points to remove dice into personal labs, adjust their values, transfer them to teammates, and prepare legal sets or runs. A contained group must share a value or form a sequence while obeying its color restriction; placed correctly, it fills one of twenty-four unique spaces in the containment matrix. Complete that matrix and Earth survives. Empty the artifact too soon or suffer seven breaches and reality is rewritten. Asymmetric scientists provide a passive ability and a powerful signature action, while research and containment cards open new tactical options. Variable threat platforms adjust difficulty, and the puzzle scales cleanly from a dedicated solo mode to four-player cooperation. The shrinking physical cube gives every decision an immediate visual deadline.
