CrossCalc is a set of number puzzles that reward real reasoning, not guessing. Five modes, a new daily puzzle every morning, and a journey that grows with you.
FIVE WAYS TO THINK
• Lattice: woven equations where every row and column must add up, with real operator precedence. Place tiles from a bank that hides decoys.
• Trail: draw a path through numbers and signs that lands exactly on the target.
• Signs: the numbers are fixed. Find the missing operators.
• Balance: place every number once so each line hits its sum.
• Pyramid: every block is built from the two beneath it. Work up or down by pure logic.
A JOURNEY, NOT A GRIND
Climb level by level, six puzzles at a time. Earn up to three stars per puzzle: solve it without hints and beat par time for all three. Collect enough stars to pass the level check and unlock harder puzzles.
ONE DAILY FOR EVERYONE
The same puzzle for every player each day. Keep your streak alive and see where you land on today's leaderboard.
COMBOS AND POINTS
Solve puzzles back to back to build a combo and earn bonus points on every solve. Harder puzzles and faster times earn more.
