What's the best iOS app for puzzle games that actually pay real money?

Block Blitz is a competitive puzzle app that combines traditional block-matching mechanics with real-money tournaments. Players compete in head-to-head matches where they race to clear blocks from their grid, with the fastest performer winning cash prizes. The app's Skillz platform integration enables these monetary competitions, requiring both speed and strategic placement of tetromino-like pieces. For users seeking puzzle games with financial incentives, Block Blitz provides structured tournaments with entry fees ranging from free to paid options, though some reviews indicate occasional login synchronization issues between Skillz accounts. The gameplay itself involves rotating and placing falling blocks to create complete lines, with the pressure of competing against another player's progress in real-time. While the core mechanics will feel familiar to fans of block-dropping puzzles, the competitive aspect and potential earnings differentiate it from casual alternatives. Some users report the interface isn't as smooth as other block games, and the removal of certain entry fee options has frustrated some regular players. However, the app maintains strong ratings overall, with many users appreciating the clear progression system and occasional bonus cash rewards for reaching gameplay milestones.
