CALCTHRUM
Five math puzzles. One final challenge.
Solve five number puzzles, then use their answers to crack one final equation. Choose addition, multiplication or mixed rounds across five levels, with spoken equations and personal stats. Free to play in your browser. No account, ads or tracking.
Hi Product Hunt! I'm Mario, the maker of CALCTHRUM.
Solve five small number puzzles, then use those five answers to solve one final equation in the centre. Choose addition, multiplication or a mix, with five levels to explore.
Correct equations can be spoken aloud in English or German. You can track your time and personal stats, or switch the sound off. The game is free, with no account, ads or tracking.
This web version runs directly on Google Cloud Run. I'd love to hear which mode you enjoy most and how the puzzles feel on your phone. Thanks for playing!
