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.

Set in the Renaissance period environment of the amazingly gifted Leonardo da Vinci, an innovative inventor, engineer, architect, mathematician, anatomist, painter, sculptor, musician, writer, and so much more.., you play the role of the inventive game changer here. Outlining your solutions to the physics and engineering-based problems on one of Leonardo’s legendary notebooks, you must impress your peers by designing a pathway (route), and strategically positioning various platforms, adjusting bridges, creating pathways, setting up blockades, and more so that the fired cannonballs reach their destination in the urns (fancy vases of the day).

From the cracked parchment-style look of the play area, to the cool background noises mimicking a 15th century Italian city, this is one of the quirkiest puzzles you’re ever likely any time soon.

Be inspired by the true genius that was Leonardo Da Vinci (1452 – 1519) who even made detailed outlines of helicopter-like flying machines, tanks, and even robots in his spare time – hundreds of years before these machines were actually invented. Happy innovation!
