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!

Who hunted CALCTHRUM?

CALCTHRUM was hunted by Mario Engel. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
