There are six levels of difficulty: White-Yellow-Blue-Red-Black and Devil's 17.

At its core, Doku provides deep satisfaction in mastering different levels of intellectual challenges step by step. Analogous to a fields and track athlete, you will be motivated by how far you can push down your average-time in each category.

However, if you just hurry along this solo quest, you may miss significant part of the Doku pleasure: Did you check out the curiously adrenalin inducing head-to-head duel? Did you know that a group of friends may email back and forth a dokugram and play against a "ghost" of one another?

Underlying such fun and competitive spirit is a robust system to keep one's Stats. In this section, details of stats management will be given.

If higher levels demand deep focus, success at lower levels require quick, special pattern recognition skills. It is not quite right say mastery of one is superior to the other. Doku recognizes this aspect by adopting the same maturity progression within each level.
There are four stages in each level: Novice-Apprentice-Mentor-Master. Maturity advances when the player successfully finishes a given number of ciphers. (for example, 10 completions are required for a Novice-to-Apprentice promotion)

When a new cipher is generated, its difficulty reflects how mature you are at the moment: it gradually shifts to harder (in a statistical sense) as you maturity progresses. Along the way, you accumulate Game Center Achievements, reward of free eCapsules, and increased recycling-rate for eCapsules. The avatar in the Stats View gradually improves its polish reflecting this progression.
