Tactica: Chess Tactics Trainer

Most puzzle apps hand you a random position and move on. Tactica works out which tactical patterns you keep missing, then drills those until you stop missing them. *ADAPTIVE DIFFICULTY Every puzzle is rated, and so are you. Tactica serves puzzles at the difficulty where you succeed about three times in four — hard enough to learn from, easy enough to keep going. * IT FINDS YOUR BLIND SPOTS Forks, pins, skewers, deflections, back-rank mates. Tactica keeps a separate rating for each of nearly thirty tactical motifs. When one falls behind, it says so plainly: "Your deflection rating is 1,290 — 180 below your overall 1,470." Then it feeds you more of them. * PUZZLES COME BACK BEFORE YOU FORGET THEM Miss one and it returns days later, timed for when you are most likely to have forgotten it. Solve one cleanly first time and it never returns — there is nothing to relearn. * EVERY PUZZLE EXPLAINS ITSELF Solve it and Tactica names the motif and how it works, so a lucky guess becomes a pattern you recognise next time. * FIVE MINUTES A DAY A short daily set and a streak. No feed, no leaderboard, nothing else competing for your attention. * PLAY A FULL GAME TOO Four difficulty levels against the computer, with your record kept. Games save automatically and continue across sessions. * WORKS ENTIRELY OFFLINE No account. No sign-in. Your progress never leaves your device. Free to play, with every puzzle included. Optional short videos unlock hints, and a one-time purchase removes ads and gives unlimited hints. There are no interstitial ads, ever.
