The basic idea is simple. Solve a Sudoku. To standardize, we'll use Web Sudoku. Pick whatever difficulty level you want. Play at different times of day and using your choice of type and settings. When you win or give up, record some data.

• Your ID (you can use your Hackaday.io name or if you want to stay private, use a UUID)
• Time of day
• Level of difficulty
• Type of entrainment used (isochronic or binaural and at what settings)
• Number of games played in this session
• Headphone use (yes or no)
• Result (time to succeed or time when you gave up)
• Notes (e.g., was sleepy; kids were noisy; classical music in background, etc.)
