Each level of this abstract puzzler challenges the player to set up a network of pipes to allow an unspecified substance known as 'flooz' to flow through as many of those as possible. The pieces are offered in random order, and there are seven different types - straight lines going horizontally or vertically, corners rotating in each of the four directions, and cross-over pieces which carry the flooz straight across horizontally and vertically. Each of these can be entered from either side. When the flooz hits a gap, or a piece which the previous piece can't flow into, the pipe is finished. Before the flooz starts flowing from its randomly-selected starting position, the player has several seconds to start placing pieces. They can be put down anywhere. However a situation that can often occur is there will be a long and complex piping arrangement set up, yet a gap somewhere remains to be filled. Players are able to replace a piece with another in the same square (to make it easier to flow the flooz that way), but for a slight scoring penalty.

Moai-kun is a puzzle video game developed and published by Konami for the Family Computer in Japan in March 1990. The game derives its themes from Easter Island; the player controls a sentient moai statue that must rescue other moai and escape each stage via a door before the timer expires. Although platforming elements are present, the primary challenge is to find a way to manipulate the objects in each stage to reach the distressed moai and rescue them while still leaving an avenue of escape to the exit door.

An indie remake was made in 2009 for iPhone, called Gem Panic, and a range of Puzznic clones called 'Puzzle Magic' have appeared on mobiles. Many games share the same basic gameplay of Puzznic but have added extra features over the years:- Puzztrix on the web and on PC, Addled and Germinal on the iPhone, Puzzled on mobile phones.

A surreal and very original game by Geoff Crammond The game plays out on a 3D landscape with hills and valleys made up of several levels. At the highest vantage point stands The Sentinel, a statue-like being with an energy draining stare, you begin at the lowest. "Energy" plays an important role, there's a constant amount in the game world and each object is worth a certain number of units - including you. The object of each level is to absorb The Sentinel and Hyperspace to the next from his vantage point. The Sentinel scans further round the landscape every few seconds - if you're caught in his gaze, or rather the square you are standing on can be seen, you'll have about 5 seconds to teleport to another location (or hit a key to teleport to a random location - which will never be higher, and may be lower than your current level) before the Sentinel begins absorbing your energy, when it reaches zero you will be destroyed. To travel a "robot hull" must be created on a visible square then teleported to, making sure you absorb your old hull to avoid losing energy. Boulders and trees can also be created, trees to block The Sentinels view and boulders can be stacked to gain higher ground. There are a few other elements to the game - on later levels there will be other Sentries positioned around the landscape. If only part of you can be seen i.e. not the square you are standing on, a nearby tree can be changed into a "Meanie" which will ultimately force you to teleport. There are 9999 levels in the game but the next level number is based on the current level + how much energy you have remaining.
