Chess vs Chessigma

One move at a time. Chess gets clearer. Chess Master breaks every opening and endgame into four learning stages — Follow, Understand, Practice, and Challenge — so you meet each line four times in a row and the moves start to feel inevitable. Study the line, understand the reasoning, reproduce it from memory, then face an AI that plays the same opening against you — learning and real matches in one flow. Four-Stage Learning Flow 1. Follow — Tap each move in sequence, tracing the line by hand. 2. Understand — Watch the line auto-play while you read why each move wins. 3. Practice — Reproduce the sequence from memory, no hints. 4. Challenge — Play an AI that uses the same opening against you. Main Features - Four-Stage Learning Flow: Meet every opening and endgame four times through Follow, Understand, Practice, and Challenge until the moves feel natural. - Opening and Endgame Courses: Sixteen classic openings and sixteen essential endgames, every move annotated with the reasoning behind it. Star ratings track your mastery. - Tactics Puzzle Training: Over 240 puzzles across six themes — fork, pin, skewer, discovered attack, mate in N, and back rank — with ELO-based difficulty matching and a daily puzzle streak. - Four AI Opponents: Bots ranging from ELO 600 to 1600, each with a distinct playing style. Configurable chess clock, move history, captured pieces, and takeback. - Progress and ELO Tracking: Puzzle ELO over time, win and loss per bot, course completion with star ratings, and stats filtered by week, month, three months, or all time. Good For - First-time chess learners - Casual players who want to study openings systematically - Intermediate players drilling tactics to break plateaus - Anyone who wants to practice alone without a local opponent or coach Core features run fully offline and no account is required.

Chessigma reviews your chess games, shows you where the points went, and turns your own mistakes into training. The app has five tabs: Home, Train, Coach, Games and Brain. FREE - Game review: import your games from Chess.com or Lichess by username, or paste a PGN or a game link. Every move is graded, the turning points are marked, and you see the better move and the evaluation graph. The Stockfish engine runs on your phone, so a review needs no account. - Puzzles: a daily puzzle to keep your streak, classic puzzles, and Woodpecker sets that repeat the same positions until the patterns stick. - Opening Trainer: learn opening courses line by line. The first lines of every course are free. - Brain Games: twelve short games with scores and leaderboards.
