# Project Entropy vs Sudoku

The clearest difference is review sentiment: Sudoku at 100% against Project Entropy's 24%. Sudoku also leads on in-app purchases (none vs 10) and update cadence (every 3 days vs fortnightly). Project Entropy's advantage is chart position (#141 vs unranked) and device support (3 vs 1). On price and ads there is nothing between them.

Both are free to download. Project Entropy sells 10 in-app purchases, starting at $9.99 per month. Sudoku asks for nothing beyond the download.

Project Entropy ships an update fortnightly, Sudoku every 3 days. The most recent releases landed on November 3, 2026 and September 29, 2026 respectively.
