# Dr Evil's Math Challenge Game vs Math Crossword

The clearest difference is ads: Dr Evil's Math Challenge Game at none against Math Crossword's shown. Math Crossword's advantage is update cadence (fortnightly vs every 91 months) and iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Dr Evil's Math Challenge Game sells 3 one-off in-app purchases and Math Crossword sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Dr Evil's Math Challenge Game ships an update every 91 months, Math Crossword fortnightly. The most recent releases landed on October 28, 2026 and October 25, 2026 respectively.
