A lesson level serves as a training level for the rest of the game, and shows most of the tiles the player can encounter. The term can refer to:

It can also refer to other similar levels in custom level sets.

All lesson levels contain hints which explain the main concepts introduced in the level. The CC1 and CC2 lesson levels were all designed by Chuck Sommerville, whereas the CCLP1 lesson levels were primarily designed by Tyler Sontag and Henry Potts, with just one being designed by J.B. Lewis.

Other level sets

CCLP2, CCLP3, CCLP4, and CCLP5 do not have lesson levels, as they use the same devices and mechanics as the original, and are meant to be played by veteran Chipsters. However, there are some exceptions:

- CCLP3 has the introductory Entrance Examination, where most of the basic mechanics are put into test for newcomers. - CCLP4 has Proving Grounds, designed around reviewing most of the games elements. - CCLP5 has Multipurpose Tool, which was initially designed to be a block tutorial from its source set.

Other uses

Other than the official CC1 and CC2 lesson levels, the term is used to identify any level made in this style, usually introducing a concept not covered in the official lesson levels or to introduce a gimmick of a specific custom level set. For example, pi.dat's lesson 3.141592653589793238 introduces the set's use of the digits of pi as a method of solving its levels.
