My only complaint, is that the surrounding hint numbers don’t disappear when you fill in a correct answer. ### 5/5 — Excellent, y compris pour les méninges *2026-04-03* Mon jeu, faire le niveau 7, puis 8, puis 9. En cas d échec retour au niveau 7. Quasiment toujours faisable, les clés ou astuces s’acquièrent avec l’expérience. Addictif. ### 4/5 — bien conçu *2025-11-01* pas de pub et bcp de grilles gratuites ### 5/5 — Very good. *2025-10-26* Very good app. ### 3/5 — So far so good [could be 5] *2025-06-21, version 3.7.5* If I had more time perhaps it would be higher than a 3 but just not enough time yet to see long term pros/cons! I’ll update as I play longer. Other than that it seems functioning accurately, no needless ads every few seconds and plenty of choices to play free games and can then add on more as your coins go up.. all in all it’s a winner so far, I’ve played for an hour straight and haven’t paid anything! Always good sign. ### 5/5 — Favorite game *2025-01-29, version 3.7.5* I love how this game keeps my brain feeling sharp and also has a sense of instant gratification from solving smaller puzzles but has the option to challenge with larger puzzles too. Tectonic for life!!!! ### 5/5 — Très agréable *2024-11-11* J’ai découvert ce jeux sur l’Express, mais c’est un format papier. Je retrouve là le même plaisir avec une écriture simplifiée. Pour l’instant que du bonheur. ### 5/5 — Très bien *2024-07-19* Jouer en ligne est un plus cela permet la possibilité d’avoir des indices en cas de blocages ! ### 4/5 — Je recommande *2024-05-27* Génial encore mieux que sur papier ! Point négatif : l’histoire des crédits abime l’expérience ### 4/5 — Great fun game *2024-02-23, version 3.7.5* Needs deep thought ## Frequently asked questions about Tectonic ### What is Tectonic?
