Choose Computer, Players or Teams. Players and Teams support 2–4 participants on one device; teammates share one hand. A pair is a square or cube card and a number card with the same value. With two participants, the first to five pairs wins. With three or four, collect all sixteen pairs: the highest score wins and equal highest scores draw.
Both 1² and 1³ equal 1. Both 4³ and 8² equal 64. Either matching number card can complete the pair; each physical card can be used only once. Collected pairs cannot be taken.
In Players or Teams mode, pass the device to the named participant while others look away, then choose Show my hand. Choose whom to ask before pressing Ask. The cards are hidden before passing to that participant to answer. Give exactly the requested card, or say you don't have it. The next turn belongs to the participant after the asker, in numbered order. Never reveal a hand on a projector where opponents can see it.
The 32 cards are dealt as evenly as possible: 16 each for two participants; 11, 11 and 10 for three; 8 each for four. You may collect a pair already in your hand as your turn. An empty hand can pass. P1–P4 and T1–T4 on collected pairs identify their player or team. Mode or participant-count changes start a new game.
Clear selection clears your choices and answer. Restart repeats this deal from the beginning. New game gives a fresh hand. Share this setup opens a fresh game, without your hand or scores. Print prints your current display on one landscape A4 side. Fullscreen keeps the same game.
