Tetris

While going for the Master trophy you will unlock the different variants.

Origin, Treadmill, and Gravity are all available from the start. As you clear these three others will unlock and become available.

To unlock the other modes you must do the following.

Flood - Complete a variation in under 4 minutes to unlock flood.

Ledges - Clear 400 Lines to unlock ledges

Laser - Complete the origin variant to unlock laser

Magnetic - In the gravity variant clear 6 lines or more in one turn by using gravity to unlock magnetic.

For this you will need to set up for 6 lines to be cleared in a straight line. Then you need to cover this hole with another block and put 6 blocks on top of it. You will then clear the line that is blocking the pieces above so that they will drop into place and you can unlock this mode. Very simple just do it on level 1 of gravity.

Scanner - Complete 3 different variants to unlock scanner

Split - Make 4 Tetris line clears in a single game to unlock split.

Chill - In scanner, clear 8 lines or more in one scan to unlock chill.

You can do this on level 1. Hold a straight block and build up your matrix so that you have 8 lines ready to clear. When you get your next straight block drop that piece in, then swap out for your held block and drop that into place and this will give you 8. Just make sure that the scanner is not going to scan in between placing the two blocks.

Flashlight - Complete any variant at level 10 to Unlock Flashlight.

Radical - Complete all other variants to unlock radical.
