Play Countdown number puzzles against the clock, or let the app find solutions to puzzles you set up. Countdown number puzzles require you to work out a sequence of calculations with six numbers whose final result is as close to a random target number as possible.
The app shows you solutions to all puzzles, and keeps statistics and leaderboards about how well you've been solving the puzzles.
