PyrSum is a math card game built on one simple rule: find pairs of cards that sum to the target, clear the pyramid, win the level.
If you love the 24 game math card game, math card solitaire, or any sum card game where mental math gives you an edge — PyrSum is the best math card game for your commute, your break, or your couch.
HOW TO PLAY
A pyramid of numbered cards is dealt on screen. A wave target is shown. Find two cards anywhere in the pyramid that add up to that target. Tap them to clear them. Find the next pair. Clear the full pyramid to advance — and watch the target change each wave.
It sounds simple. The first few levels are simple. Then it gets interesting.

THE EQUATIONS GAME ANGLE
PyrSum is, at its core, an equations game — except the equation is always A + B = target. The strategy comes from the board. Which pairs are available? Which card do you save for the next wave target? Which combination clears the most options?
These decisions make PyrSum more than math with cards. It is a puzzle that happens to use arithmetic. The mental math happens automatically.
