Wow! I’m actually teaching a course on puzzles, and Countdown is in there, along with Krypto, the 5-card and target variant here in the US. This app is a fantastic implementation of Countdown, with a great interface for playing, a solver (looks a lot like dcode.fr!), and a great menu of different game difficulties! I am impressed because a friend of mine and I tried to code a variation of Krypto that had 4 cards and a target for iOS, and it was difficult. Again, great job, and I encourage you to continue to develop this app with more game variations, and maybe even more operators!
