Reached the end of the levels. I saw they added some levels and was excited. Paid the $0.99 for no ads. Was happy to. I went in to the app a day later to play and got a notification from my bank that I was charged $34.99 by apple. I immediately checked my app acct and saw that it was for this game “time limited offer 500”. I didn’t get an offer to click on, I didn’t get the apple confirm to buy double click. I tried finding what this offer was and couldn’t find it. I reported it immediately and my request was declined by apple. I submitted an appeal explaining the details and was denied the appeal. I wouldn’t have made this purchase as I didn’t have the funds in that account AND I don’t spend that much on a game. I just checked the App Store for the game and in the list of in-app purchases there is no listing for anything that costs $35!!! I have deleted the game - I refuse to support a game that rips off its customers. Apple has always been fair when I’ve had issues with apps but for some reason not this one. So now I’m writing a review and filing a fraud complaint with my bank. ### 2/5 — Gute Spielidee mit frustrierenden technischen Mängeln *2025-06-26* Das Spiel an sich ist unterhaltsam und hat definitiv Potenzial. Die Mechanik macht Spaß, auch wenn sich die Gitter mit der Zeit etwas wiederholen. Leider trüben gravierende technische Probleme das Spielerlebnis erheblich. Ich spiele auf einem neuen iPad Air (11 Zoll, M3-Chip) – also leistungsfähige Hardware – und dennoch friert das Spiel regelmäßig, gerne im letzten Gitter ein. Es reagiert dann nicht mehr, was weiteren Fortschritt unmöglich macht. Besonders ärgerlich: Ich habe die Vollversion gekauft, um die Werbung zu entfernen, aber nun komme ich wegen technischer Fehler gar nicht weiter. Das stellt den Mehrwert des Kaufs leider in Frage. Zusätzlich wurde mein Spielstand von einem Moment auf den nächsten vollständig gelöscht, obwohl ich bereits deutlichen Fortschritt gemacht hatte. Das ist extrem frustrierend. Liebe Entwickler, bitte behebt diese technischen Probleme dringend. Das Spiel hätte es wirklich verdient, stabil und zuverlässig zu laufen. ### 4/5 — Me encanta pero… *2024-12-27, version 4.8.4* Un clásico que me acompaña hace muchísimos años, pero del que cada vez que cambio de teléfono pierdo el progreso y tengo que comenzar desde cero, porque no tiene forma de conectarlo a una Red social o con una cuenta con la que se pueda retomar donde dejó. Una lástima. ### 1/5 — Full of scam apps ads *2024-10-19, version 4.8.4* It used to be a fun game but now it’s full of ads after every single try and they are all scam ads promising you were going to win a bunch of money by playing other apps. Don’t download them they are scams. I am deleting this app. ### 5/5 — Still one of the best games around *2024-08-28, version 4.8.4* Been through it twice now. Play a game or two each day. Shame there aren’t more like this one, it challenges and makes you work for results. When you lose five lives, it’s time to go on to something else! ### 5/5 — Hi *2024-08-25, version 4.8.4* Hi ### 5/5 — Good Game *2024-08-11, version 4.8.4* No issues.. makes you think ### 3/5 — Best without sound *2024-07-01, version 4.8.4* This game is quite ‘morish’, and gets more and more challenging, making it more attractive, however the sounds are most unpleasant and I have to turn them off to be able to play the game. ### 2/5 — Getting to be an aggravating game *2024-06-25, version 4.8.4* As you progress you will find that it gets to be a bit aggravating to play. Too many ads, (every minute or two), it almost never gives you the amount of time that it tells you you will have to complete the level…it will tell you perhaps 1 min 18 seconds and you might get only a few seconds…I have timed it…. it repeats a lot of the same challenges in the levels. ### 3/5 — Fun but….. *2024-06-23* I do enjoy playing this game however, it does get frustrating as it gets into the higher levels. It appears to repeat a lot on some of the challenges and the timing is off. It may tell you you have 30 seconds or 1 minute to do the challenge but it closes almost immediately after you begin. I don’t know whether it’s counting the ad times in that 30/seconds or 1 minute or not however, the timing is almost always shorter then what they tell you it is. Makes it very hard to complete unless you ‘buy’ extra time, which I don’t do. ## Frequently asked questions about Riddle Stones ### What kind of game is Riddle Stones - Cross Numbers?
