## What is Ergo Chess?

Sharpen the part of chess that wins games: seeing the tactic and finishing the mate.

ErgoChess is a focused trainer built around a huge, curated puzzle library and a progression that actually teaches. Start with simple back-rank mates and climb — each checkmate pattern unlocks the next as you master it — until the full tactics trainer opens up.

WHAT'S INSIDE

• Checkmate trainer — ~18,000 puzzles from mate-in-1 to mate-in-5, organized by pattern (back-rank, smothered, and more) so you drill the ideas that recur in real games.

• Tactics trainer — ~60,000 puzzles across 20 themes (forks, pins, skewers, discovered attacks, sacrifices…), each with a difficulty band, sourced from the Lichess puzzle database.

• Play vs the computer — a real Stockfish opponent with adjustable strength, plus a built-in fallback engine so you can always get a game.

• Famous games — replay and guess the moves of legendary games, with a link to a video breakdown of each.

• Daily puzzle & streaks — one puzzle a day to keep your streak alive.

• Track everything — a personal dashboard with your tactics rating, accuracy, solves over time, mates by pattern, and tactics by theme.

• Friends & leaderboards — add friends, compare on a friends-only leaderboard, and follow each other's activity.

• Favorites — save any puzzle or game to revisit.

Your progress syncs across web and mobile, so you can train on your phone and pick up right where you left off at ergochess.com.

Free to play. Sign in with Apple, Google, or email.

### 5/5 — Worth Downloading

*2026-10-03*

Great approach to teaching the strategy and mate tactics. Noticeably faster improvements to rank.

### 5/5 — Easy to use and my rating has noticeably improved

*2026-09-26*

Really good chess trainer! I like that the puzzles are separated by actual patterns instead of just giving you endless random positions. I’ve gotten noticeably better at spotting mates and tactics during games. There are a ton of puzzles too, plus Stockfish and the famous games mode. Been using it pretty much every day and already seeing a bump to my elo

### 5/5 — Simple and fun!

*2026-09-25*

Simple and easy to use. Looking forward to improving!
