Use reaction skills, keyboard control, analytical thinking skills and hand-eye coordination to guide the little guy to the exit.

Reasons to play this cool brain teaser adventure game: Test and exercise your problem-solving / solution-finding skills, motor skills, reflexes, and more as you try to figure out the best way to guide the little mothball to the exit portal while avoiding enemies.

Strategy to win: Remember the core goal – To get Mr Mothball safely to the exit. Although it might be tempting to collect all of the Dust Pellets and try spectacular jumping moves, this is no use if it puts the little mothball in danger!

Steep Dive Airmail is a fun and challenging "point, drag and click"-based puzzle game for kids & teens where you must carefully plan out the flight path of a small aircraft so that it collects all of the loose mail along its route. Using your analytical thinking skills with good strategy and timing, you must ensure that your plane flies safely across the game screen while coming into contact with any awkwardly-positioned mail. Before take-off, you manually set the dotted flight trajectory of your aircraft so that it enables you to reach each piece of mail in that level while avoiding other flying aircraft, hot air balloons and rockets.

This stimulating brain teaser challenge should prove a good fun test for fans of interactive problem-solving activities, logic and creative engineering games online. The air traffic control tower may just have found itself a new star!

Play an interactive, sliding tile puzzle game with 100 levels on your mobile phone, tablet, notebook, laptop, or desktop PC! Car Parking is a challenging problem-solving, strategy brain teaser game (for elementary school kids, where you must use your car as a tool to strategically push large boxes around a confined, maze-like parking lot. Featuring a simple top-down view and board-style layout, you must methodically move the crates into position on specific parking spots marked with a ‘P’. This can prove tricky as the boxes can only be pushed forward (one move / step at a time), and each of the 100 levels takes place in a very small car park where space is limited and your moves must be carefully planned.

This difficult, online, HTML5-based, strategy / problem-solving puzzle game should work on iOS and Android devices as well as most web browsers for PC / Mac. To play the game with full screen, you may have to turn your device horizontally. Each mini maze puzzle requires a combination of logical and analytical thinking skills, strategic planning, step-by-step analysis, and the ability to think outside the box – Pun intended! Patience, determination, and high levels of concentration are really important here. A willingness for trial and error is also key – You can restart levels as often as you like, and there are no time restrictions.

Tip: Move slowly in measured actions, with one arrow key click or one tap touch per move (Do not make very quick clicking or tapping actions as the game sometimes does not accept such moves as valid). When the crate is successfully accepted into its placement, it turns red in color. If the box does not turn red in its final placement, it means that the game software has not accepted your overly-swift movement into that parking position.

Are you ready to build up your chances of reaching the high score? It’s time to lay the foundations of victory! Good luck and enjoy!

Beginners beware – later levels feature extremely complex step-by-step solutions that can only be achieved through rigorous trial and error.

Online Turnz Game is a brain teaser puzzle game that not only develops your logical thinking skills, but guarantees you hours of fun as well. Your aim is to help the purple guy “BLOB” to reach the finish by rotating his world. The BLOB, as well as the BLUB (who does not have to get to the finish) moves around only when you turn the game screen. A rock does not move and has no other effect other than just being there as an obstacle. A breakable rock gets destroyed after one hit. There is also a teleport block. Place two or more of these on the screen.

If you place more than two of these, they will each teleport to the next one (3 teleport blocks: 1 teleports to 2, 3 to 3 and 2 to 1). The bomb block explodes after a set time. It can be set by the person who creates the level. The death block resets the game when a player’s block hits it. You will also encounter locks with the same color keys. If the blue key is hit, the blue lock becomes passable, however, if after that the yellow key is hit, the blue block and its key become visible again and the yellow one becomes invisible. The BLOBS can enter the purple doors and the BLUBS – the green ones.
