## What is Problems.cc?

Problems is a daily dose of beautiful maths puzzles from Exact Science.

Every day you get a new set of bite-size challenges designed to sharpen real mathematical thinking — not just pattern-matching. Solve them in a couple of minutes, build a streak, and come back tomorrow for more.

FOUR DAILY GAMES
• Crossnumber — solve interlocking Across and Down clues to deduce every digit.
• Cryptarithm — each letter stands for a different digit; crack the code so the sum is correct.
• Magic Square — fill the grid so every row, column and diagonal add up to the same total.
• Summit — slot operations between the numbers to hit the target.

WHY YOU'LL LIKE IT
• A new puzzle every day, with a full archive of past days to play.
• Streaks and progress tracking to keep the habit going.
• Clean, calm design with a light and dark theme.
• No ads. No pre-game interruptions. No sign-up required to play.
