'''Lesson 4''' is the fourth level in [[Chip's Challenge 1]]. This [[lesson level]] is significantly more complicated than the last three, teaching [[Chip]] about [[tank]]s and [[blue button]]s, [[toggle wall]]s and [[green button]]s, and [[tile]]s that can be hidden under [[block]]s.

'''Lesson 4''' is the fourth level in [[Chip's Challenge 1]]. It was designed by [[Chuck Sommerville]]. This [[lesson level]] is significantly more complicated than the last three, teaching [[Chip]] about [[tank]]s and [[blue button]]s, [[toggle wall]]s and [[green button]]s, and [[tile]]s that can be hidden under [[block]]s.
To complete Lesson 4, Chip can move through the three rooms in any order. The room with the tanks is to the left of the starting room, the room with the blocks is underneath, and the room with the toggle walls is to the right. In the room with the tanks, use the blue buttons to move the tanks out of Chip's way to collect the [[computer chip|chip]] at the top. Use the blue buttons again to move the tanks to get out of the room. In the the room with the blocks, move the corner blocks to collect the four chips. Don't move the middle block, as it [[hot block|has fire under it]]. In the room with the toggle walls, use the green buttons to switch the toggle doors to collect the chips. Once Chip has gone through all the rooms and collected all the chips, he can then go through the [[socket]] and walk to the [[exit]], thus completing the level.

== Version differences ==
In the unreleased [[NES]] port, the [[fire]] beneath the central block is replaced with a [[wall]], rendering the block immobile.
