Chip's Challenge is a game originally for the Atari Lynx but later bundled with the Best of Windows Entertainment Package. It involves the eponymous hero, Chip McCallahan, who has met Melinda The Mental Marvel in the school science laboratory and must navigate through Melinda's "Clubhouse" (a series of 149 increasingly difficult puzzles) in order to prove himself and gain membership to the very exclusive Bit Buster Club.The gameplay involves Chip moving about a number of tile-based 2D levels involving things like cloning machines, ice and force floor puzzles, and various monsters, attempting to finish a level before the time limit runs out. A sequel has been produced, adding numerous gameplay elements, but due to legal issues has never been released.Fans have created several Level Editors for the game, with which thousands of additional levels have been created. Some of the most well received of these of these were assembled into the Fan Sequels CCLP2 and CCLP3 (CCLP short for "Chip's Challenge Level Pack").
Level 18, Castle Moat. The apparent solution is to push blocks into the moat to make a bridge across. Under one of the blocks is a powerup that lets you simply swim across.
Most levels have a Chip Socket blocking off the exit, which can only be cleared by collecting the required number of chips first. In Level 20, the designers forgot to put this in, so collecting chips is unnecessary, making the level much easier.
Thanks to a possible bug, it's possible to pass through one-way floors in the wrong direction if you are sliding on ice. This makes several puzzles trivial.
Thanks to another bug, some clone machines will fail to clone a monster in certain situations, and some monsters stuck in traps will stay in them even if the trap is released. This also makes several puzzles trivial.
Frictionless Ice: Even more than the Block Puzzles; level 136, Doublemaze, uses this to create two overlapping mazes...
Hailfire Peaks: Every level where the four major elements (water, fire, ice and magnetism/suction) are equitably present. These levels include level 3 (Lesson 3), level 15 (Elementary), level 40 (Floorgasborg), and level 48 (Mugger Square). A closer relative to the actual Hailfire Peaks is level 124, Fire Trap, whose puzzles and obstacles are entirely based on fire and ice. Level 75, Steam, is a maze made of fire and water.
Level 138, Partial Post. The exit is right at the start, except a teleport tile will prevent you from reaching it. You need to lock all routes so that the teleporter has no option but let you walk to the exit.
In levels 46 and 66, the chip socket (which only open when all chips are collected), forks its route into three, only in one of which the exit is; in the other two, you'll fall into a trap that forces you to repeat the current level.
Marathon Level: On The Rocks, Cityblock, Pain, Writer's Block, Chipmine...and they're all nightmarish to play.
Mercy Mode: Blow a level enough times and Melinda will reward your perseverance and let you skip it. You have to actually waste enough time on the level first, however.
Mind Screw: Level 111, Time Lapse. For one, the level has unlimited time; secondly, the level's mechanics doesn't seem to work coherently in the PC version. Are the bugs in the northwestern portion supposed to press a green switch that locks the entire inner area of the level (because they don't)? The reason for these weirdnesses is due to the gameplay differences from the Lynx version. In it, the green doors leading to the exit are toggled permanently after a while because the bugs do manage to reach the button that activates the switcheroo. One of the many porting errors gives you much more leeway.
Level 18, Castle Moat. Either spend the 10 minutes you get pushing blocks all the way around the island until you've got enough to walk to it safely... or go to the top right corner of the maze and find the hidden flippers.
The Microsoft version has a bug that lets you complete Level 60, Scoundrel, by forcing your way across the force floors surrounding the exit square.
Secret Level: Levels 146 through 149, accessible only when you crack a code in level 34.
Shout-Out: Level 73, Morton. It is named after singer and talk show host Morton Downey Jr., and your primary enemy is the teeth (an allusion to the talk show's logo).
Time Keeps On Ticking: when reading the hints located on the question mark circle tiles. Although it doesn't really matter, since you can pause the game while you're reading them. (When the game is paused, the action window is covered, but the info window, where the hints show up, is not).
Trial-and-Error Gameplay: Multiple levels, including Cellblocked and Icedeath. Take the wrong path and either you're stuck or dead. Cellblocked even tells you at the beginning how to restart the level.
Special, the true final level, dumps the player into a huge room full of blocks. Every single block has fire underneath it, except for one that's covering the exit.
