The chess engine runs right in your browser, so the first time it needs to download about 52 MB. Once downloaded, the browser keeps it and you can play instantly next time.

The engine uses your device's processor to calculate. At the strongest levels and during long analysis your device warms up; closing the analysis screen when you're not using it helps.

Beat the previous character once without Undo and Hint. Little Na, Uncle Tư and Teacher Lan are free; your first game with each character after them is a gift, then 100₫ a game.

There are 8 ranks, from Novice to Sage, and you have two separate ranks. Your online rank follows your xiangqi Elo: reach the Elo on a gatekeeper character's card to rank up (Little Na's 600 makes you Apprentice…); if your Elo drops below the mark your rank drops too, but the highest rank you reached is kept; others see this rank on your picture frame. Your vs-computer rank: beat the gatekeeper 3 times (no undo, no hints) to collect 3 stars and rank up. See both on your Profile.

Pick a strength from level 1 to 10, no need to climb the character ladder. Levels 1–3 are free; from level 4 games are paid.

After the game, the computer reviews every move and explains it in plain English. Without a top-up you can read the coach for 1 game a day; with money in the wallet, every game.

A new puzzle every day for everyone, plus a library by category and difficulty. Solve every day to keep your streak; your puzzle rating moves with the puzzles' difficulty. Puzzle rush: solve as many as you can in 3 minutes; 3 mistakes and the run ends.

You need to sign in. Without a top-up you get 3 hints a day; with money in the wallet, unlimited. A puzzle solved with a hint is still marked solved, but your puzzle rating counts it as not solved.

14 short lessons, from how each piece moves to tactics, classic mates and endgames. Each has a position to try on the board. Free for everyone; sign in to keep your progress across devices.

The most common ways to open a game, step by step with their ideas. From any move you can open the analysis board and continue against the engine.

More than 2,000 games between grandmasters at major events (Chinese national individual and team championships, the Five Goats Cup, Asian and world championships…), filtered by player, event and result. From any move you can open the analysis board or play on against the computer.

The openings, master games, analysis board and position editor all have a button to play the computer from the position on screen. Such games are just practice: no Elo, rank stars, unlocks or win missions; the usual game fee applies.

3 small missions every day (play, win, solve a puzzle, study a lesson…). Finish all 3 to get 3 free games.

Everyone starts at 500. There are three Elo ratings: xiangqi (online games, with bullet, blitz and rapid counted together), jieqi, and vs-computer. Pairing and the leaderboard only use the xiangqi and jieqi Elo. A game against the computer counts as a game against a player with the Elo on the character's card: beating a stronger character earns a lot, beating a weaker one earns almost nothing. Games that used Undo or Hint don't count for Elo.

The Elo range widens gradually; after 25 seconds you're paired with anyone waiting. After 30 seconds you can play a computer character of your level while you wait: for the next 30 minutes, if anyone looks for a game with the same time control you'll be notified on any page — tap Accept to join.

You have 45 seconds to come back. After that, a game in progress counts as a loss.

If time runs out before one side has made a move, the game is aborted and doesn't count for Elo. The game fee still applies, because the game had started.
