Fun and challenging, minimal Ads!
Sun Feb 04 2024 iPhoneusernotbychoiceMuch better than the first nuts and bolts option that comes up. That one is just a bunch of long Ads and you can never move forward without watching 35 of them every five seconds. And it’s timed, if you miss the time window, here’s some more Ads! 😡This one is challenging, but fun, only a few ads and you have the option to pay $4 if you don’t want ads forever. I mean, if that’s something you despise.. but one every now and then I don’t care about. And they’re not long. Not like some other games that have three 4 min ads. Ain’t nobody got time for that!! Thank you for making a fun game and not punishing us for wanting to play it!
Please report this app as a scam!
Wed Sep 04 2024 Coconut water x2I was really enjoying the game, I even paid to remove the ads. Now I understand the business model, it’s a ‘free’ game and then you get folks to watch ads or pay, which I totally get, but I paid $3.99 to be able to play, without having to watch an ad. So far so good! That is until you get to level 77. There are no holes, only the extra hole, so you’re forced to either watch an ad, or use diamonds. And if you mess up, well you’re forced to watch an ad or buy diamonds. I can see right now how my future is going to look and that makes me really hate the shady side of this business model, and sadly this game. I’ve wasted $5.99 only to be forced to pay more (which isn’t told to you upfront btw) so here’s your warning now. Even if you pay, it’s still not going to be free. And it’ll just get worse and worse the higher the level you go. Update, so I updated the app to fix bugs, so it says, but now you have 5 hearts as lives and if you use them up then you have to watch an ad or use diamonds. This is a total scam cause I NEVER signed up for that. I don’t understand why games like this have to resort to shady tactics, when the game itself is good enough to stand on its own. I understand ads for free games but if you want to pay just to enjoy the game as is, without the tricks, then just offer that. I WANT MY MONEY BACK!
Addictive game but with annoying issues
Thu May 09 2024 OldHarKelI became addicted to this game and was thinking of giving a 5 but then issues popped up. I did not mind watching the ads to get an extra hole for a hard puzzle, but At upper levels it brings in "lives". You get 5 lives before having to watch an ad or pay for more lives. After the 5th reboot of a hard puzzle it forces watching the ads to continue, giving only one life each time. The nail in the coffin (or screw as it may be) was when my lives were all used up with a puzzle that had the annoying rocking bears and no open holes to move a screw to. The bears were covering the holes. This had happened before but a reset (using up a life) opened a hole to start. The last one was reset three times with no open hole either time and using my last lives. The fun has gone from this game. I am deleting it.
I’m enjoying the game
Tue Oct 10 2023 Morning100Nuts and bolts review I just completed 100 games on this new app. It has become one of my favorite games. If you read the critics they will tell you that there are too many ads or it is boring or that it occasionally repeats. First, I seldom write reviews but this is a new game and if one wants it to succeed or fail, write a review. Mine is for its success. I must admit, I’m ad tolerant. I think of ads as someone else paying for me to play the game. We are interrupted by commercials on TV and we are paying for the TV! Plainly put the game is not boring. While some levels are quite easy others are more challenging all are fun to solve. Does it repeat? Perhaps I have experienced one or two but I’m not complaining. This is a new game with at this writing fewer than 300 comments. Give them a break as they continue to improve this game. I personally like it. No I don’t know anyone that has any relationship with the producers. I’m just liking the game.
Purchases not applied. No support
Tue Aug 27 2024 Memorize999I enjoy the game but only when it works like it’s supposed to! I’m also someone willing to make in app purchases to make the time I spend more enjoyable. I’ve paid for “VIP” passes twice now and they have not been fully applied either time. Usually they only work for a couple of days, or only some of the embedded rewards are applied. I’ve tried updating, “restoring purchase” and I’ve also reached out to the developer via their site (form doesn’t work) and email (no response). Again, I’m happy to pay, I just want to get what I pay for!!! Another issue I will mention here — there are several levels that are impossible (no empty spaces from the start). This means I have to watch a video or purchase “gems” to skip. Super frustrating.
Ads galore! Game goes black!
Sun Jul 28 2024 janpzDon't pay to have ads removed! I paid $5.99 to get no ads! What a waste of money! I see no difference in the number of ads I have to endure. The game itself is fun and challenging, but if you don't finish a puzzle before the time is up, you have to watch an ad. Want to reset a level? Watch an ad. The only way to escape watching ads is to pay for "unlocks". Want to reset? Watch an ad. Game play and ad watching take equal parts of time. I was going to silently put up with the ads, but now the game has gone dark. I closed the app and reopened. I've turned the phone off and back on. The app opens to the point where I click on the button to start the level and it goes black. I can escape from the game and everything else on the phone is fine. I see others are complaining about the black screen.
Not bad, but…
Thu Dec 07 2023 HobbesMamaThe puzzles can definitely be tricky, but none so far have been impossible (although I have had to add an extra hole a time or two to get myself out of a jam.) However, I was extremely disappointed to find that after a time the puzzles just started repeating, and it quickly became very boring because it was too easy to remember the secrets for success. The only way I’ll really enjoy this again is if I put it down for a long time and give myself a chance to forget. This defeats the entire purpose of having a game to play, in my eyes. I want a game that is fun for more than just a day or two.
Ads and more ads
Sun Mar 03 2024 Bronxbaby126I read the only review here where the person said there weren’t many ads and they could play for a bit before an ad popped up. Not true. I got 4 plays, which are quick, it’s not difficult at all so it’s not like any time is spent on the game. And then an ad. The arrows showed up to move forward, it took me to the app to download, I declined. And it went back to the ad. Had to wait for it to finish. Played ONE game after that and the ads began. Yes, I understand it’s how they get paid and how it helps the creators keep things going. I’m just asking for a better, harder game where I spend time working on it, gimme a few of those and THEN an ad. It’s like the game interrupts the ads at this point. Deleted the game.
