### 4/5 — Incorrect levels reported

*2025-09-02, version 3.0.11.7*

I am playing through partner app for coins. I give you praise for a wonderful game, with great tools that help achieve high levels. But today my levels are correct in game app, but incorrect on partners app, therefore not paying coins. If can’t solve problem I have no reason to play. They say must be handled on your end.This takes mental capacity to play these games, and endure these long grueling ads. Still waiting for rewards

### 3/5 — New update

*2024-11-10, version 3.001.35*

I dont like the new update

### 3/5 — Kind of Jen

*2024-08-24, version 3.001.35*

There are a lot of inappropriate ads, and I was not able to claim the rewards for Web tunes overall fun game, but I just want my Web coins

### 3/5 — Graphics

*2024-08-20, version 3.001.35*

Not a fan of the new graphics seems cheaper loved the game before couldn’t get enough but now I don’t want to play it as often

### 5/5 — The game makes you think and develops your reasoning skills.

### 4/5 — Fun time killer

*2024-06-26, version 2.011.94*

### 4/5 — This game is Addictive!

*2024-05-25, version 2.011.94*

I love this game is really addictive when I play it everything is good, from the graphics to the mechanics! But there’s way too many ads. So I don’t play frequently but when I do I’m too addicted to click off!

### 1/5 — Frequently locks up, WAY too many ads

*2024-05-23, version 2.011.94*

This game frequently locks up and the only way to proceed is to close the app and reopen it. In doing so, you lose your game progress. This happens a lot preceding an ad or just after. Right now it locked up just as I was about to place my last block to win a game. Sometimes the ads are at least a minute long. I was playing a Sudoku game by this developer but had to quit because of the ads - ads popped up DURING the game every minute or two and totally took over the screen. I’ve played a lot of games and have never had that. This game plays ads during the game but they are minimized either at the top right corner or at the bottom. Sometimes the game locks up while those play. This developer’s apps are the worst I’ve ever played. I’m interested in the developer’s response.
