Leave London and circle the globe in 80 days, beating 50 rivals on the board. The AI thinks on your device, so it is just as strong offline. Play people online too.
A steampunk Reversi race around the world, where every board you win is a patent seized. The AI thinks on your device, so you finish every game offline.
You leave London. 80 days to circle the globe and win back the patents you lost — on the board.
■ The game is Reversi
Place black and white discs on an 8×8 board and flip the ones you trap. Legal squares are marked for you.
A minute to learn, and no ceiling on how good you can get.
■ 5 chapters, 50 legs
London and Europe, Transcontinental Express, Desert Ruins, Cities of the Far East, Sky Fortress.
Each match costs 1 to 3 days. The cleaner the win, the fewer days it takes.
Get home within 80 days for the true ending. Go over and the journey continues, but the record keeps the overrun.
■ From leg 1 to the Peerless of leg 50
6 grades — Novice · Beginner · Intermediate · Advanced · Master · Peerless — tuned so the gap to the next leg stays small.
You will not fall into the hole between "hopeless" and "too easy".
■ The first few games find your level
Play 3 to 7 calibration games and the app proposes the leg where you will be evenly matched.
■ The AI thinks on your device
No board position is sent anywhere to choose a move. Underground, in the air, out of range — the same strength, down to the last move.
■ Replay the game afterwards
Open the logbook and step the board back one move at a time to see where it turned.
During a game you may take back up to 3 moves per match (against the on-device AI only).
■ Play people (online matches)
You are paired automatically with a nearby rating. Wins and losses move your rating and put you on the leaderboard.
Opponents and the leaderboard see your profile name (or a server placeholder); report abuse in-game. No chat, no other free text.
In online matches the moves and the result (record, outcome, rating) are stored on the match server.
■ A review of every game, free of charge
Ask for a review in the logbook and the AI reads that game and explains the turning points in words.
It costs nothing and needs no purchase; one review per game.
The move record is sent to the AI through our server at that moment. Nothing is sent unless you ask.
■ The AI’s inner voice
A short line shows what your opponent is thinking, chosen to match what just happened on the board.
The lines are picked on your device: nothing is sent, and it costs nothing. On by default; you can turn it off in Settings.
■ What builds up
Every game is recorded: your win rate and the spread of legs you have played.
25 achievements unlock on their own once you meet the conditions.
Your rank follows the strength estimated from the games you have played.
■ Portrait, one hand
Portrait only. The board fits the width of the screen and legal squares are marked.
Sound effects, music and the inner voice each switch on and off separately, with their own volume.
■ Ads, and the one-time "Remove ads" purchase
The app is free. Ads may appear between games.
A single purchase of "Remove ads (lifetime)" removes the ads and opens the scoring of how you play and the AI coach's advice.
Optional: every leg is playable without it and the post-game review stays free.
"The Engine-Master" (one-time purchase): an animated avatar that becomes your face. Looks only; no effect on strength or rules.
"The Navigator" (one-time purchase): a second animated avatar, looks only.
■ No sign-up
No account needed. We do not collect your name, e-mail address, phone number or date of birth.
Games against the on-device AI, your settings and your achievements stay on this device.
An anonymous account that is not tied to your name is created automatically only when you start an online match or buy/restore the one-time purchase.
Note: resetting the device or deleting the app loses them. There is no transfer between devices.
■ Age rating
Intended for ages 13 and up.
