Solid version of 'Tetris' on 3DS, while the loss of online features might hurt it today, they were a good inclusion for the time. The tuning of the game itself is pretty much perfect, presentation is solid, and it has a decent suite of modes. Marathon is rendered a bit redundant since clearing level 15 isn't the highest demand the game could ask of you, but it does unlock the standard endless mode one is after. Sprint and Ultra feel like the expected timed modes you find in any 'Tetris' game worth its salt and they're alright if a bit unimaginative. Battle and Battle Ultimate kinda suck though, the TetriBot is pathetic and doesn't hold up much of a fight at all, you're much better off doing some local play with friends for that sort of experience. The challenge modes are neat though and certainly worth ones time. Overall its fine, not as interesting as something like 'Puyo Puyo Tetris' or 'Tetris Effect' but I prefer the presentation quite a bit more over something like 'Tetris: Axis', but I suspect that title is more feature packed and therefor considered the ideal 3DS 'Tetris' release.
