# Arrovex Flow vs Sudoku

The clearest difference is ads: Arrovex Flow at none against Sudoku's shown. On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Arrovex Flow sells 2 one-off in-app purchases and Sudoku sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 25, 2026 and October 31, 2026 respectively.
