CenterCross: Math Crossword
Math Logic & Number Brain Game
Free · Designed for iPad. Not verified for macOS.
1,000 math crossword puzzles where every line points to the center. Pure logic, no guessing, from Very Easy to Grandmaster. Play offline, anytime.
CenterCross is a math crossword where every line points to the center. Fill in the missing numbers so every sum is true: a calm, clever number puzzle you can play offline, anywhere.
Each card is a small equation, like 37 + ? = 61, and every card's line leads to the number in the middle. Drag the right tiles into the blanks, find the hidden signs, and solve the whole board with pure logic. Easy to learn, hard to put down.
1,000 PUZZLES
Start with gentle addition in Very Easy and work up through Easy, Medium, Hard, Expert, Master and Grandmaster. Every level brings something new:
• Addition and subtraction with carrying and borrowing
• Hidden signs: find the missing + − × ÷
• Blank centers: work out the middle number from the clues
• Two puzzles on one board in the hardest levels
Finish a level to unlock the next one.
PURE LOGIC, NO GUESSING
Every puzzle has exactly one solution, and every one can be solved step by step by logic alone. No luck and no timers rushing you: just you, the numbers and a satisfying "aha!" when the last sum clicks into place.
