Play a cool, fun and addicting interactive puzzler: Exercise and sharpen your cognitive and problem-solving skills with this challenging and stimulating puzzle game where you must position 5 elevators between the 21st and 25th floors using math-based logic! Elevators Logic is a real head-scratcher of a game for older kids (8+ year olds), high school teens and adults - combining ordinary addition and subtraction logic with a passion for solving brain teasers. In this tough puzzle, your ultimate goal is to open the doors of five elevators and free the elevator occupants. 

Unfortunately for the passengers, this set of elevators operate on a bizarre system full of quirky rules! They must move two at a time, and can only go up 8 or down 13 floors at a time! Another big catch is that the elevator doors will only open when ALL FIVE elevators lie between the 21st and 25th floors inclusive! Phew! With all these rules, you just know this is going to be tricky, and immersive!

Reasons to play: This fun visual and logic-based puzzle should prove a rewarding activity for those who enjoy interactive mind games that are built on simple concepts with tricky challenges attached! It could also be used as a fun reinforcement activity for cognitive learning & development. Test and exercise your analytical thinking and cognitive skills, common sense reasoning, problem-solving determination and stamina as you strive to get all of the elevators to the required floors! Sharp math skills (requiring simultaneous adding and subtracting) also come into play as you try to visualize and solve in advance the best way to get all five elevators to where you need them to go.

A lot of potential trial and error is required – so you need to be patient – The solution is there somewhere! Be prepared for a proper challenge.

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.
