Finalo: Chess Endgames

Finalo teaches chess endgames one topic at a time. Each topic starts with a short explanation in plain language on two or three positions, continues with puzzles, and in seven topics ends with a game against the device, which defends as long as possible. You learn to win won positions and to save lost ones. Everything ships with the app: it works without an internet connection, with no account and no ads. 17 TOPICS • Basic mates: mate with the queen, mate with the rook • Pawn endgames: opposition, the square rule, key squares, the outside passed pawn, pawn breakthrough • Rook endgames: the Lucena, Philidor and Vancura positions • Minor pieces: the wrong-coloured bishop, knight against pawn, bishop against knight • Queen endgames: queen against pawn, queen against rook • Advanced (optional): mate with two bishops, mate with bishop and knight • No topic is locked; if you know the basic mates, start with pawn endgames 4 LEVELS • Beginner, Intermediate, Hard and Expert: puzzles come from the level's rating range (above 2300 at Expert) • A personal rating per topic: puzzles get harder as you solve them • At higher levels, games against the device start further from mate, with less leeway over the shortest path • Mastery is counted separately for each level EXPLANATIONS • Two or three positions per topic, with marked squares, rings and dots • Terms explained in plain words, and an "In short" summary • Written by Finalo, in 11 languages PUZZLES • 2,610 endgame puzzles from the Lichess puzzle database (public domain, CC0), sorted into topics by their material • The goal (mate or win) is shown above the board • Two-step hint, Show solution, Try again; step through the moves AGAINST THE DEVICE • Queen and rook mates, king and pawn endings, two bishops, bishop and knight • The device plays the longest defence; perfect tables computed by Finalo itself, no external engine • How many moves are left, the quality of each move, the best move, take back • Feedback only on mistakes, on every move or at the end PRACTICE AND PROGRESS • Mastery: a topic is complete when 80% of recent puzzles are solved on the first try (and the game is won close to the shortest path) • Today's set: 5, 10 or 20 puzzles from your topics and the review queue • Spaced review: positions you get wrong come back after 1, 3, 7 and 21 days • Streak, weekly strip and a 12-week activity grid BOARD AND FILES • FigBell's own pieces, board colours, square names, move sound • Move by dragging, by tapping two squares, or with the keyboard • Share a position as an image with its FEN • Save your progress as a .finalo file and open it on another device; back up and restore Available in 11 languages, in dark and light themes, on phone, tablet and computer.
