1. Enjoy a game of Go against the strongest AI, KataGo, easily on your mobile device.

. A top-tier advanced AI Go engine that surpasses professional players.
. Improve your Go strength anytime, anywhere, right from your mobile device.
. Since the Go calculation runs on a powerful GPU server, there is no burden of device heating or battery drain.
. Choose your desired playing strength from a total of 30 levels, combining 5 KataGo levels and 6 reading-depth levels.
. There is no time limit for games, and your games are saved automatically.
. You can continue your game anytime.

2. Tsumego

. Includes over 27,000 tsumego problems by rank, from 30 kyu to 9 dan.
. Earn stars based on the number of attempts used to solve each tsumego problem.

. Ask KataGo to find the top 3 recommended moves for the next move.
. View the variations KataGo expects for each recommended move.
. Improve your Go strength through recommended moves and variations.

4. AI Position Judgment

. Unlike humans, AI does not simply count territory. It judges the position by estimating the strength of ownership.
. Ownership is displayed by the size of squares, allowing you to understand how AI evaluates the position.

5. A New Type of Go Game

. Compete on equal terms with “Opening Game.”
. Even professional players find it difficult to play an even game or one-stone handicap game against KataGo. But what about limiting the game to the opening?
. Within the first 60 moves, choose the first 5 moves and play the opening you want.
. See how AI responds to various openings. Before long, you may find yourself becoming stronger in the opening.

6. AI Recommended Moves and AI Position Judgment in Try Mode and Review

. Beyond simply trying out moves, you can use AI Recommended Moves and AI Position Judgment on either Black’s or White’s turn to understand various possible developments.
. Playing against a good teacher is important in Go, but review is just as important. Since AI Recommended Moves and AI Position Judgment are also available during review, you can study effectively.
