# Sudoku vs Brain Calculus

The clearest difference is ads: Brain Calculus at none against Sudoku's shown. Sudoku's advantage is iOS requirement (12.0 vs 16.2). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
