# Killer Sudoku vs Extra+

The clearest difference is in-app purchases: Killer Sudoku at none against Extra+'s 1. Killer Sudoku also leads on iOS requirement (13.0 vs 17.6). Extra+'s advantage is update cadence (every 10 days vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. Extra+ sells 1 one-off in-app purchase. Killer Sudoku asks for nothing beyond the download.

Killer Sudoku ships an update every 4 months, Extra+ every 10 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
