+The rules for the movement of [[teeth]] and [[blob]]s, as well as [[animation delay]] in [[Lynx]], are governed by the principles of '''odd and even step''', and are vital mechanics to understand at high levels of [[Chip's Challenge]] play.

 == Using odd and even step ==
-For exploiting such occurrences, [[Tile World]] is generally preferred, because simply pressing ''O'' allows the player to manually toggle the modes at the beginning of a level. The word (odd) will appear next to the [[time limit]] when odd step is selected. In MS, however, because of the continuing clock counter, the algorithm is harder to control. The CC window will always begin in even step, so it is easy to select even step. Odd step is much harder to select, since it depends on the player switching over to the desired level exactly [1/2] after the clock ticks - not enough to cause the clock to drop, but enough to cause the level to begin on an odd tick.
+For exploiting such occurrences, [[Tile World]] is generally preferred, because simply pressing ''O'' allows the player to manually toggle the modes at the beginning of a level. In versions 1.x.x of Tile World, the word ''(odd)'' will appear next to the [[time limit]] when odd step is selected, and will remain there the entire time the level is being played; in Tile World 2, however, the words ''odd-step'' will appear below the [[hint]] box and will not remain there for the rest of the level, as the same box is also used to display onomatopoeia of game sounds when the game's volume is set to 0. In [[Microsoft's version of Chip's Challenge|MSCC]], however, because of the continuing clock counter, the algorithm is harder to control. The CC window will always begin in even step, so it is easy to select even step. Odd step is much harder to select, since it depends on the player switching over to the desired level exactly [1/2] after the clock ticks - not enough to cause the clock to drop, but enough to cause the level to begin on an odd tick.
-MS CC users can use [[Fullsec]] to easily toggle between odd and even step, but it is harder to use than Tile World's control. The F5 control will start the level, unlike the ''O'' control, such that unless initial waiting is required, the level has to be started again. Odd step in Fullsec can only be detected by looking at the Best Times submenu, whose ''U'' is capitalized during odd step mode.

+== Lynx ==
+In Lynx mode, there are actually 8 step parities as opposed to only 2. The "new" step parities include even+1, even+2, even+3, and their odd step counterparts. Pressing the ''O'' key will still toggle odd and even step, skipping the +1, +2 and +3 parities, but pressing ''Shift+O'' will advance one step parity at a time. This can be used to more precisely control teeth and blobs, but it is also useful in controlling animation delay, as how long it lasts for is actually dependent on the current step parity. For more details, [[Animation delay|see the page]].

-In this small mini-level, the time limit is 20. The [[blob]] is restricted between U and D forever, and guards the [[blue key]]. To exit, Chip must snatch the blue key, then open the [[blue lock]] at [0, 1], on the teeth's moving turn, in order to free the exit. Chip must then lure the teeth ''just'' out of the way to reach the exit before getting eaten.

Chip must then lure the teeth ''just'' out of the way to reach the exit before getting eaten.
-The fastest way is in odd step, as after sliding on the [[ice]] and moving L, Chip now has to wait only [1] before getting the key (also avoiding the [[Transparency Glitch]]), instead of [2]. Now, Chip can collect the key, slide back, and open the [[blue lock]] without waiting. Now, move (2D 2R [3]) U to exit, with 15 seconds remaining. Waiting [4] would allow the teeth to match Chip's second L move, rather than the first U move, and he could not escape in time; waiting only [2] does not put the teeth on [2, 2] at all. As this route is a [[Chip's Challenge scoring|15.0]], using even step will only score 14.
