Chess vs Chess64

Chess-3D helps add new layers of flexibility to your brain’s perceptual machinery as you exercise your mind planning strategic defenses and bold attacks into another dimension. All pieces move in the same basic formations as 2D chess, but now with the option of vertical-movement components in 3D-space. Simply select a piece with a mouse-click, select the squares distance to move it and then a 3D or 2D directional arrow to reach the square you are targeting. Invalid moves are rejected. It really is that simple. You can play against someone on one device as the boards rotate after each move, online against friends via Game Centre or against the computer AI. For visual clarity red pieces are traditional-chess white pieces and blue is black. User controls allow you to rotate and zoom to easily see piece positions.

Chess64 is a checkmate trainer. The puzzles never ask you for the best move, only for the forced one: every one ends in mate, and the whole difficulty is how deep the line runs and whether you can see all of it before you touch a piece. WHAT YOU GET • Eight depths, from a one-move mate to the long forcing lines of mate in 8+. The app carries 400k+ puzzles, completely offline, with 50,000 at every depth. Each one is generated for this app and verified by a chess engine, so the mate is forced and runs to exactly the depth stated. (What the free tier reaches is set out under FREE AND PRO below.) • Spaced-repetition training. A puzzle you have solved comes back at growing intervals, timed to reach you just before the pattern would have faded. You set how many new puzzles and how many reviews you want in a day. Beside it, a curated library of openings and the traps that spring from them. Every trap line is proved by a chess engine before it ships, and drilling one puts it in the same review queue. • Five bots to play against, each with a style of its own. Win enough of your recent games against one of the bots and the app tells you the next one up is a fair fight or not. Afterwards the review analyses the game: the tactics that were there, which of them you found, and the move that you missed. • Pass and play: two people, one device, and no engine in the middle. Free. Leave the board where it is, turn it between moves, or turn only the black pieces so each player reads their own the right way up. Play with a clock or without one, and start a piece up or a piece down. These games are not added to your record or your statistics. • A daily puzzle: one mate in 3, the same position for everyone, every day. • A timed challenge: solve as many as you can before the clock runs out. Three wrong moves retire a puzzle and the next one arrives. • Statistics that keep accuracy and solve rate apart instead of blurring them together, plus an activity calendar, results by depth, time-of-day performance, and the depths you are weakest at. Export all of it as CSV (Pro). • Home-screen widgets: your streak at a glance, plus quick actions on the medium size. WHAT IT DOES NOT DO No ads. No tracking, no analytics, no third-party data collection of any kind. No account, no sign-in, no email address. Chess64 never asks to track you across apps. The daily reminder stays off until you turn it on, and you choose the days and the time, so nothing arrives unannounced. FREE AND PRO Free covers mate in 1 and mate in 2, with 5,000 puzzles at each of those two depths, plus the daily puzzle, full games against the first two bots, pass and play games with somebody next to you, streaks, badges, core statistics and the streak widget. No ads and no time limits. Chess64 Pro is one purchase, not a subscription. It unlocks the other three bots and the review that follows a game, mate in 3 to 8+ with the full 50,000 puzzles at every depth, a difficulty filter from Beginner to Master, the timed challenge, spaced-repetition training, the openings library and its traps, hints, full statistics with CSV export, and the medium widget. Later updates are included. The price is shown in the app and on the App Store in your own currency. YOUR DATA There are no Chess64 servers. Your progress backs up to your own private iCloud, comes back when you sign in on a new device, and syncs across your devices without passing through anything in between. Turn iCloud off, or use no iCloud account at all, and Chess64 works the same way it always does; your progress simply stays on the one device. Every puzzle ships inside the app and the bots think on your device, so once you are set up you can play with no connection at all.
