Contamination Rounds

Contamination rounds are rounds where the board is heavily contaminated with biohazards.

In these levels, make sure to clear off as many biohazards as you can, and use the chromium atoms to your advantage, as the biohazards can quickly and easily choke off the board. There are 5 contamination rounds. It is highly recommended that you use your atomic bomb on the last two, as they are really hard due to a lot of colors in them.

Contamination rounds: 12 (4 colors), 22 (6 colors), 26 (7 colors), 34 (9 colors), 37 (11 colors)

Hint box
''We've got a bit of a problem here. All the meso-resons from the last round caused a sub-level conjunctive neo-quark to phase right through our meta-plane spectrum.''

''This grid is heavily bio-contaminated! Clear them out before they spread!''
