Build equations, call Higher or Lower, and outsmart friends or the computer.
Build an equation from your cards, hide it, and make everyone guess wrong.
EquationClash is a strategy card game where math meets bluffing. Every number card counts, every operator changes the story, and the best equation is the one your opponents can't read.
QUICK CLASH
• Build a 2- or 3-number equation from your hand and play it face-down
• Everyone else calls it: Higher or Lower than the last result?
• A right call scores 10; fool them and you score 5 for each
• Tied at the end? Sudden death until one player is out
GRAND CLASH
• Get 1 hidden and 2 open number cards, then swap one for a fresh card or keep your hand
• A 4th card arrives: now build your equations
• Use all 4 numbers with your +, − and ÷ to aim at 20 (High) or 1 (Low)
• Bonus × and √ cards change everything
• Secretly declare High, Low or Swing, then reveal together
• Ties go to the best colour card: Gold, Silver, Bronze, Black
• Win a side for 10 points, sweep both with a Swing for 25
