Atoms

Atoms are the main gameplay element in Atomica. Make a 2x2 square of 4 atoms to make a molecule and remove it from the board. You can also make a 2x3 double molecule. They come in 11 colors.

If you turn on the colorblind option, atomic symbols appear on the atoms.

Trivia

 * If you look in the Atoms.jpg file in the images directory, there is a 12th color, gray, which is unused. It does not appear in the action mode, and when you get past level 41 with 11 colors, level 42 is empty. It might have been just there for testing purposes, but you can get it in a level by hacking the save game file, which is hard to do.
 * If you manage to get the gray atom by hacking the save game, it will have a Cr symbol, similar to a chromium atom.
 * The orange atom has a swirl design, similar to a yin yang symbol. The light yellow atom has a greenish tint to it and a zig zag design. The light blue atom has a grayish-yellowish outer ring on it.
