TOO MANY ADVERTS

I can understand you having adverts between levels but in the middle of every level is both ridiculous and obtrusive.

MOST ADS OF ALL TIME

A month ago, this was my absolute favorite game. possibly my favorite app even. But this past month is been ads every 2-3 minutes. Absolutely frustrating and insane to think this can continue without losing players

Ridiculous

It’s bad enough you put so ads in this game, which is definitely not necessary, not this many, but you’ve also failed the players by not saving their progress in the challenges when the game decides to glitch and close or a phone call comes in and needs to be answered. It sets you right back to the beginning, all progress lost. It’s ridiculous.

Overheating

The overheating is unacceptable. This is a very simple number puzzle game, yet my phone gets extremely hot after only a short period of playing, and the battery drains unusually fast.

What makes it even more concerning is that the overheating still occurs when playing offline, so this does not seem to be caused only by ads or network activity. A game this simple should not put this much load on a modern smartphone.

Please seriously investigate the app’s CPU/GPU usage, rendering, and background SDK activity. I enjoy the game itself, but the excessive heat and battery drain make it difficult to keep using.

4 adds per game

Good game, unplayable with 4 adds per game… and too expensive “no ads” purchase for what is offered. Milking the player to the max….

Ad infested!

Love the concept, but to be repeatedly interrupted during a single game with ads? No. Deleting it now.

Great game but …

I thought this was one of the best games, challenging and fun. I have no objection to ads between games, but several right in the middle of a game disrupts the flow of thought. Going to delete it now, just too irritating. Another criticism is that the sum of the coloured square is too small for me to see easily. Such a shame, I was really enjoying it.

Ads Galore!

Great brain game but the ads are completely out of control. It’s an unnecessary amount, too bad cause it was be an excellent way to keep the brain busy.

Such a shame

A really good game completely spoiled by an excessive number of advertisements. I have downloaded and played many games in the last 20 years but this is the worse. Adverts not only appear after completing the game but several time’s during the game. I could pay for ad free but normally accept a reasonable number of ads.

Needs work

The program has problems that need to be addressed. Low shadow color difference from white. The inability to change the write-erase switch for a flop-flop to a specific click switch selection. The inability to disable the animations to eliminate the delays when making selections or clicking the flip-flop write-erase selection.

Nope

Very fun game but pop up ads in the middle of a level - no thanks!

Pop up ads frustrating

Love this game but the pop up ads in the middle of the puzzle is frustrating because they happen just as I’m finishing a line. Ad is one that continually pops out to the internet and seem to take forever to end. Likely will only play this once in awhile because it is not relaxing to have to deal with ads during the game. UPDATE: Received apology and promise to look into my complaints from the developer but they have told others the same thing for at least 2 years. Sounds sincere but no changes erases that.

Ugh

I lose most of my hearts by forgetting whether I’m in pencil or eraser mode. Some color would help, or make it buttons rather than a toggle switch. If I touch the pen while already in pen mode it toggles to eraser. Ridiculous design.
If I’ve circled every number that needs circling, and all my sums are correct, the extra numbers should delete automatically. Having to run around with the eraser after the puzzle is solved is insulting.

Ads in the middle of gameplay

I like the concept of the game and the layout, but an ad will pop up in the middle of your strategy you can easily forget your train of thought by the time your ad is done. I understand the need for ads to provide free gameplay, but that is not cool.

Number sums

If only there were fewer adverts, this is such a good game but the level of adverts is ridiculous. It’s a game to use your brain and it interrupts all the time with adverts that it’s so easy to loose where you were. Had to get rid of it, was driving me nuts!!!!

DARK MODE PLEASE

This game is great for sharpening my brain in between obligations but I beg of you, please give it a dark mode. Sometimes I play before bed and I’m just murdering my eyes with the bright screen.

what

Fun game but just stupid, there are multiple solutions to every number, but you don't find the right one unless you get some wrong, and the 3 lives are just gone by then, dumb design.

Toooo many ads

Great game totally ruined by in game ads. I understand ads are necessary, however this many ads will make me delete the game.

SO MANY ADS

Ads when you open the game. Ads in the middle of puzzles. Ads after every level. Uninstalling after only a few levels.

Too many ads

Understand the need for ads, but having ads pop up in the middle of a level breaks your concentration.
I enjoy the game but will likely choose to uninstall because of the interruptions. Awful.
