DTT  There was a bug where scores were not being uploaded for some players but that was fixed with the latest version of the game.

The high score from the player in Japan is real. None of the scores are inflated or inaccurate. There really are people that good at the game who know how to optimize their scoring while doing amazingly fast line clears.

As another person commented, you can pause the game with the Escape key or any other key you assign to Pause.

SYHARRIS  This is a reasonably well done rendition of Tetris, with deficiencies that make it rather crippled.

As the previous reviewer pointed out, there's no undo function...important when accidentally placing a falling tile in the wrong space.

There's no selection for difficulty level, the tiles fall at just one speed, which is most often too fast for proper placement when the stack of tiles nears the top of the playing area.

And there doesn't seem to be a way to accurately keep record of your score.

The high scores of players around the world, reaching into the upper hundred thousands, just isn't believable; especially when important functions like those mentioned above are not available.

SYZZYGY  While the sound/graphics are nice, the game features are lacking.

There's no undo function to take back a wrong tile placement, no pause function, no difficulty level to choose from.

While your score and ranking vis-a-vis other players worldwide is maintained on Tetris Zone's website, it doesn't seem to update your stats to reflect your actual standing.

I managed a highscore of 97,000 once but my stats state that my highest score is 32,000.

The all time high score is stated as being just under 875,000 by a player from Japan, with other players managing high scores of in the upper hundred thousands, but somehow I just don't think such scores are really possible.

While skill and fast thinking play a big part in doing well in this game, chance does play a fairly big role in that it depends on the right tile falling at just the right time.

Sometimes, it seems that the pieces fall at too great a speed to allow for accurate placement, but there's no way to slow it down.

I purchased this game and do rather like it, but I feel that it could better by providing it with the features mentioned above.
