User Reviews

Players enjoy the calming, brain‑teasing puzzle and offline play, with varied modes and a flexible hint system. However, recurring problems include heavy ads and stability glitches (crashes/freezes) and occasional hints/UI bugs, which significantly affect the experience for multiple users.

Pros

Calming, engaging puzzle that feels unique and brain‑teasing.
Multiple modes (Endless, Challenge, Timed) offer varied pacing and challenge.
Playable offline without WiFi.
Flexible hint system (option to earn clues by watching ads or buy clues) that adds accessibility without forcing a single path.

Cons

Excessive, intrusive ads (full-screen video ads, including after leaving the app) that persist even for some users who paid to remove them.
Stability issues like crashes and freezes (startup crashes, blue dot crash) disrupting gameplay.

I liked this until the “free hint” button popped up…and froze the game. Closing the game and opening it didn’t help, nor did shutting down my device. I finally uninstalled and reinstalled it, losing all progress. I started again and after just a few levels, it’s back. 5 stars for an enjoyable game, 1 star for the bug.

A simple game of addition with an almost crossword form. Endless is your basic zen mode of playing and becoming familiar with the game. Challenge and Timed is for having the added difficulty of beating the clock. This game plays without WiFi. The game doesn’t detect your default language, so if you want English you need to enter the game’s settings. You will know you’re in the right area when you see the list of other languages. Either than that, this game is good.
