The ancient strategy game of Go meets cutting edge technology with Igowin HD. With the most powerful Go software available for the iPad, Igowin HD will challenge you no matter what your level, and keep you at the top of your game, on small boards or full size. Its user friendly features make Igowin HD the perfect app for beginners and experienced players alike. Igowin HD uses the same Go engine as The Many Faces of Go, the three time world computer Go champion. It draws on more than two and a half decades of experience, a massive knowledge base and the newest research, as well as modern Monte Carlo techniques to help you learn and grow as a player. Designed specifically for the iPad, it takes full advantage of the iPad's faster processor to bring you the strongest computer Go opponent available anytime you're ready. Igowin HD supports play on 9x9, 13x13, or 19x19 boards. This flexible program lets you set your rank as you like. Game parameters can be set up automatically based on your playing level, or you can choose whatever opponent strength or handicap you want. Igowin HD has an all new, extensive Review Games feature that lets you save and review completed games or games in progress. Try new variations at any point in a game and continue playing against the computer from there. Mark stones and add comments to any game for later study to improve your play. The iPad's large screen and Igowin HD's updated, hi res graphics are ideal for game review. Virtually anything you can do with an sgf reader, you can do right on your iPad with Igowin HD, and you can email the game complete with all your changes to your PC. The iPad's large screen makes it easy to place your stones where you want it, but Igowin HD also has a built in "magnifying glass" to help you place stones accurately. Smart move technology snaps your stone into the correct position. The convenient "instant-undo" feature lets you reset a mis-tap without waiting for the computer to finish thinking. Igowin HD has a comprehensive tutorial of rules and basic strategy. You can learn the game basics quickly and begin playing immediately. You can ask for a hint or an estimate of the current score anytime during a game. With no complex menus and just a few basic controls, the game is easy to navigate. All AI levels are calibrated by actual play, on an online server. That means that the ranking Igowin gives you is very close to what your real-world ranking would be, rather than an arbitrary number that only applies within the app. Igowin HD uses the traditional Kyu ranking system to measure your performance. The engine automatically adjusts its level of play to match yours. By using the calibrated rankings within the Go engine, it can play a 9x9 even game, with no handicaps, against any player, from beginner all the way up to 3 Dan level. 19x19 even games automatically adjust from beginner to 3 Kyu. Whether you're a rookie looking for a fun way to learn and play the game of Go, or a crafty veteran looking for a challenge, Igowin HD is the app you've been searching for. Take Igowin HD wherever you go, and play it whenever you have a few minutes to burn. It's always ready for a quick game, or a long session. With Igowin HD on your iPad, you're ready to start playing the 4000 year old game that takes a few minutes to learn, and a lifetime to master.
