They spiked my game and right when I was going to get a high score, the arrows did nothing and I couldn't move my blocks all of a sudden...

This extension pops up AI art ads without you knowing, Be cautious of downloading this, it will most likely be used for malware in the future.

This is a virus/adware. Every now and then when you open chrome, this extension automatically opens AI websites which are loaded with viruses and often explicit. I like the game but if you're thinking about adding this extension, find another one that does the same thing, don't get this one.

not very responsive and injects ads into your browser

Fun game with a few minor problems here and there. But the real turn-off is the ads that are injected into your browser (solution is to block the following domains: k-ext.pages.dev and k-ext-ads.netlify.app).

if i could give this a 0/5 i would injects ads into your browser without telling you

Randomly opens ads for AI tools and extensions in a new tab. The game unfortunately doesn't have a hold piece function and the colours are different to normal as well.

I believe this extension opens spam AI tabs without permission. Pop-ups and redirects are allowlisted for no reason

The generation for the blocks is completely wrong, some pieces have a higher change than others. L pieces and long pieces spawn and seemingly irrational ordering. For example, you could go forever without getting a long piece and then just have it spawn three times in a row. The random function that they used seems completely broken and not mathematically random at all. This happens with several pieces where you don't get them for an absurd amount of time and then you get 2 or 3 in a row. Fix your damn game

I was playing at around 800k and it just suddenly restarted by itself. My cursour wasn't even on the restart button. Please fix this bug and this game is trash.

The game is honestly garbage for a Tetris clone. First of all, the big issues. You can only rotate the piece in one direction which limits a lot of t-spins. Furthermore, 180 degree spins do not exist which is also a big issue but luckily, there is not as much use for 180 degree spins as there are for counter-clockwise spins (which don’t exist in Tetrys). Also, there is no option to hold pieces which is a key factor in the actual Tetris game. Not only can you not hold pieces, but the next few pieces cannot be seen, so you cannot plan into the future, which is another big part of Tetris. The least you could do is show one piece, but even that is not there. Another huge issue is the randomizer. Tetrys uses a completely random piece generator (sometimes known as total mayhem and is exactly what the name suggests). This means that you can get 5 O pieces in a row, completely screwing up the board and destroying your setups. Also, you will experience severe piece droughts when there is a piece dependency. In normal Tetris, the default randomizer is 7-bag, meaning in each cycle, the 7 pieces are randomly shuffled, and after you get seven pieces, the next cycle begins. This is a huge factor in Tetris, not only for planning into the future, but used for a lot of t-spin setups and all clear setups. All clears are not virtually impossible and same for t-spin factories such as TSD setups. Also, openings are thrown out of the window. Furthermore, a HUGE issue is the fact that hard drops DON’T EVEN EXIST. Hard drops are one of the most important parts of Tetris that allow you to quickly place pieces with precision while on Tetrys, you have to wait slowly for pieces to soft drop down. This is insanely terrible and very annoying. Now onto the smaller issues. First the lock delay is atrocious. When you soft drop, there is virtually no time to move or rotate the piece after you drop it down. This makes it very difficult to complete t-spins (if you can even do them with the only clockwise rotation). It also makes it very difficult to slide pieces under overhangs. Next, there is no setting to change the soft drop or any other setting like the side to side movement speed. This severely slows down the game. Also, without a way to change SDF, it is so bothersome to even attempt to do t-spins that you will mess up anyways because of the garbage lock delay and rotation mechanisms. Another small issue is that even if a little bit of a piece is over the red line, you die instantly, whereas if a bit is poking out in normal Tetris, you still survive. There are a lot more issues, but these are the main ones. Please don't play this extension if you are looking for Tetris. It is laughable that the creator is asking for donations. There are plenty of website that offer much better versions such as tetris.com and tetr.io. I personally enjoy tetr.io.

Sadly I cannot give 0 stars. this is such a bad fan version of tetris, you cant hold, none of the mechanics are even close to tetris. They make the version bad by removing all of them. The fact that he asks for a donation, is just sad. Higly recomend not to play.

fun tetris game to play whenever until you realise that it doesnt actually use a good randomiser and you can and will get ten yellow pieces in a row and then a green and three more yellow pieces. literally makes me want to shoot myself in the foot.

What the hell? The DAS is way too fast, there's no hard drop, just the simple act of dropping a piece gives you points, the arrow keys being the controls are really bad, only allowing for one-directional movement. There's nothing to differentiate it from all of the other bootleg rip-offs. If you really want to play a version of Tetris for free, just go onto Jstris. It feels better and has multiplayer, overall just a solid version, the go-to simple, competitive clean version of Modern Tetris.

Horrible game that will make you rage. Horrible game. The further you advance in score, the unluckier you get. It almost seems as if the game is purposely giving you the worst possible blocks you can get later in the game and the arrow keys and WASD keys don't work very well, sometimes they will register one click twice and others it will just ignore your frantic clicking as a block falls in a spot which later kills you after you had spent hours on the game and it would all just end from pure unluckiness or horrible controls.

This version of tetris is worse than a knockoff. It would be much more enjoyable if there was an algorithm, instead of getting a random block, it's *too* random. Also, there are many glitches and errors in this game that make it unfair. If you want people to play a game, or if you want to rip off a game, then actually *try*.

If I'm going to be honest this game has one major flaw, sometimes it lags and won't let me move the pieces which really frustrates me. One time I got really mad since I was trying to get my high score which is 50305, I was literally a few hundred away and then I couldn't move my objects, keep in mind my wifi when I was playing was perfectly normal and my device did not cause the lag. >:|

This is a fun game, but the randomiser is horrible. Sometimes you get the same piece 5 times in a row. Also, there are certain times where it doesn't seem random because many times, I'll need a green piece, but I have to put something in the slot where the green piece needs to go and then naturally, the next piece that comes is green.

It controls poorly and it's hard to tell where a piece will drop. Not very fun.

I don't mind how this is a fun little pop up game, the only problem with it is you can't see what's your next block. Without this information, how can you plan your next move?

It's an okay game but I've choked so many times because there's no hold slot, and the RNG seems to give me the same pieces four or five times in a row a lot. The game also only gives me blocks at some points from a pool of three pieces, which i find really annoying when I get four squares and two s-pieces in a row. Edit: Literally 2 minutes after I posted this comment I died while Tetris-ready because it kept only giving me the R block, the S block, and the O block, literal garbage randomiser
