Plumber is a highly stimulating and challenging puzzle game where you have to re-arrange and connect a set of jumbled individual pieces of pipe in order to create a continuous pipeline that allows water to flow from the starting tap through to the end point (the overflow pipe). Under serious time pressure, you have to quickly rotate the various bend pieces and straight piping parts so that they form a viable channel for the water to travel through. Once your pipeline is complete, you can start the flow of water and progress to the next challenge!

This innovative maze-based, construction game requires quick logical thinking on your hands and knees (You have less than 45 seconds to construct a pathway for the water in each level). This problem solving brain teaser is an ideal activity for players who enjoy a fast-paced puzzle with a real-life concept (everyday plumbing issues). Good observation and decision making skills are important (Will you spot when you’ve made an error in direction?) If you realize that you have started down an impossible pathway early enough, you might just have enough time to rectify the situation. Plumbing and water routing sure can pack a brain-teasing punch! Let’s see how far your pipeline building skills can take you!

How quickly can you enter numbers to break the code under intense pressure while playing the part of a cheeky rogue? Art Thief is an unusual yet fun code-breaking puzzle game (based on deductive reasoning) where you have to quickly and logically figure out the 3-digit code that instantaneously switches off an alarm system so that you can grab and run off with valuable loot (paintings from prestigious museums). In this suave virtual world, your character is a normal, corporate office worker by day, and the world’s most notorious art thief by night, attempting daring heists in some of the most renowned galleries! Known only as ‘The Specter’, you have scrupulously designed a state-of-the-art code breaking gadget that handily indicates whether your 3-digit guess is ‘higher’ or ‘lower’ than the real alarm code in that gallery. Through a series of logical guesses and quick reactions, you try to crack the alarm code to switch off the laser system, and steal the painting!

The more valuable the painting – the less time you have to work on the code! So, have you got the skill and desire to break the code? Good luck – and just don’t trip that alarm!

Create a viable electricity pipe channel (connection) between the two electric glowing sources, against the clock! Connection is a challenging online visual puzzle game where you must methodically re-arrange (slide) jumbled tiles on a large grid in order to create a continuous pipeline where electricity flows freely from the start to the end point.

Puzzle Freak 2 is a collection of fun educational puzzles and riddles of various difficulties that challenge your mind and thinking skills. It is a great game when you have your friends over or family gathering. You can play against the computer or your friends or a mix of both. The game does not only test your IQ, but involves you into puzzle solving for hours. You must go around the board game, and beat your opponents while completing the most puzzles in the shortest time. The faster you complete a puzzle, the more IQ points you earn and you get another turn to roll your dice. If you cannot solve a given task, you must pass the dice onto the next player. In a way, it is very similar to Monopoly.

There are 4 types of puzzle squares you can land on, and they differ in level of difficulty (easy, normal, hard and very hard). You earn more IQ points for the more difficult puzzles. There are “Chance” squares on the board, marked with a question mark, which may help or hinder you on your way to the finish line. You may select a different board before you begin the game by clicking on the arrows, located on the left and right sides. The boards differ in their field arrangement and in their game time (very short game, short game, long game and very long game). After you choose a board, click 'Play' to start the game. Using your computer mouse, click on the dice to throw. After each rollout, you will get a new puzzle to solve.

All of the puzzles are time-based. Read the task description at the bottom of the screen and then click on the game screen to begin solving the puzzle. There is an example shown before the puzzle is started. Watch it closely to understand what is required in order to solve the problem. Make sure you understand the assignment well, and only then click anywhere on the game screen to start solving it.
