A hundred thousand rated puzzles, bundled in the app. On a plane, on the subway, off the grid. No account, no ads, no catch.
Every decision points one way: more time on tactics, less on everything else.
All 117,121 puzzles live inside the binary. No download, no sign-in, no waiting on a connection that is not there.
Solved it? Keep going against a 2300-rated engine and prove the win is really there. No guessing whether you found the point.
Puzzles meet you at your level. Your rating climbs, and per-theme stats show exactly which tactics still need work.
No account. No ads. No tracking. Your history, rating, and settings never leave the phone. Delete the app and it is all gone.
Most trainers show a green checkmark and move on. Here, when the tactic lands, the position stays live and the engine fights back. You have to actually convert.
No subscription, no upsells, no ads waiting behind a paywall. Try it free every day; unlock the whole thing for the price of a coffee.
Twenty rated puzzles every single day. No account required.
