# Dudoku vs Sudoku Labs

The clearest difference is ads: Sudoku Labs at none against Dudoku's shown. Dudoku's advantage is update cadence (every 2 days vs weekly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Dudoku ships an update every 2 days, Sudoku Labs weekly. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
