# milliSudoku vs Tap Arrow 3D

The clearest difference is in-app purchases: milliSudoku at none against Tap Arrow 3D's 10. milliSudoku also leads on ads (none vs shown). Tap Arrow 3D's advantage is update cadence (fortnightly vs every 3 months) and iOS requirement (13.0 vs 18.0). On price and device support there is nothing between them.

Both are free to download. Tap Arrow 3D sells 10 one-off in-app purchases. milliSudoku asks for nothing beyond the download.

milliSudoku ships an update every 3 months, Tap Arrow 3D fortnightly. The most recent releases landed on October 24, 2026 and November 5, 2026 respectively.
