Ich habe mir das MegaPack mit allen 150 Rätseln geholt und es macht einfach nur Spaß!! Dazu kommt keine Werbung UND keine Zwischenrätsel, die man lösen muss um neue Logicals freizuschalten. Würde mich über neue zukünftige Rätsel freuen wobei ich jetzt erstmal beschäftigt bin:)) ### 2/5 — Misses the mark *2026-01-08, version 8.0.4* This game doesn’t quite fit on the screen, causing the user to have to use a slide to go back back-and-forth. It also doesn’t have an easy way to correct your mistakes once you figure them out. Plus the user interface is a bit David. There are plenty of other logic apps out there that are better. ### 5/5 — Vielen Dank für diese App! *2025-12-23* Es ist so erfrischend, dass diese App werbefrei ist. Tolle Logicals in allen Schwierigkeitsstufen. Als absolute Frechheit empfinde ich dass die ein oder andere Rezension die kaufbaren Level als „überteuert“ betitelt. Wenn ihr, nachdem ihr 9 Tolle Logicals lösen durftet, keine 1,99€ für weiteren Knobelspass übrig habt, geht doch einfach zu McDonalds und kauft euch für das Geld einen halben Cheeseburger. Jeder Cent den Sie, der Ersteller dieser App, durch die Level-Erweiterungen verdienen, sei ihnen vom Herzen gegönnt. Vielen Dank für diese App. ### 5/5 — Super Spiel *2024-09-19* Super schlanke Bedienoberfläche, sodass man beim Rätseln von nichts abgelenkt wird. Die Rätsel sind ebenfalls sehr verständlich. Würde mich über schwerere Rätsel freuen. Außerdem sind die Rätselpack etwas „rätselhaft“ beschrieben. Ich würde mich freuen, wenn es eine Info gäbe, wann neue Rätsel kommen, denn ich habe alle gelöst :) ### 5/5 — Toller Tüftel-Spaß *2024-08-21* Diese Logik-Rätsel kenne ich noch von früher vom P.M. Magazin. Sie machen total Spaß und die grauen Zellen werden ordentlich gefordert. Und endlich habe ich dafür diese tolle App gefunden. Die 6 kostenlose Level haben mir gleich wieder Lust auf mehr gemacht, und ich habe sehnsüchtig auf die Freigabe des angekündigten PuzzlePack Y00 gewartet, bei dem alle 150 Puzzles inklusive sind. Dabei hatte ich einen sehr netten Kontakt zum App-Entwickler Christian Lueth. Heute wurde der PuzzlePack endlich freigegeben, Christian hat mich sofort darüber persönlich informiert. Den Preis von 13,99€ find ich sehr angemessen, dafür habe ich nun wochenlang was zum Tüfteln. Vielen herzlichen Dank😊. ### 1/5 — Only 6 levels *2024-06-10, version 7.6.6* Why are there levels & I have to pay so much for new levels ### 5/5 — Satisfying to Figure Out *2023-11-29, version 7.6.6* The first time attempting these puzzles took me hours, but as I went on, I realized that it involves some of the skills that I learned playing Sudoku. I enjoyed it very much and re-solved some of the puzzles so that I could better my time significantly. I only wish that there were more puzzles to solve. Thank you to the creator. ### 5/5 — super! *2023-11-15* Liebe die Art von Denksporträtseln und ärgere mich, die App nicht schon früher gefunden zu haben. Die Bedienung ist sowohl am Handy, als auch auf dem macbook super. Für die paar Euros, lohnen sich die ganzen Rätsel die man bekommt. ### 5/5 — Netter Denksport gut umgesetzt *2023-01-11* Tolle Darstellung auf dem iPad, eingängige Bedienung, faire Preise für weitere Rätsel. Ich habe inzwischen alle Rätsel gemacht (E01-E45, M01-M46, H01-65) und vermisse jetzt Nachschub, um weitere Rätsel zu lösen. ### 5/5 — Great Brain puzzle *2022-12-29, version 7.6.6* Really well made game with easy mechanics but challenging puzzles ## Frequently asked questions about Logicals ### What kind of puzzles does Logicals offer?
