Fun Da Vinci is a straight-forward, interactive physics-based puzzle game for both younger and older kids where you have to move and place objects in ideal positions so that cannonballs can be fired and directed into designated urns in each level. 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).

The gameplay and graphics of this atmospheric brain teaser makes it feel like you are being immersed in a Renaissance drawing board. 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. As in all physics-based puzzle games, your observation skills, problem solving and strategic planning abilities, determination, stamina and patience are sternly exercised and tested. 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!

However, you only have a limited number of balls available in each level, so your aim must be perfect!

Skills required: This hard and stimulating shooting ball / brain teaser game combines tactful, pinpoint mouse clicking skills with analytical thinking and creative engineering problem solving. Utilizing some knowledge of gravity, trajectory, and the kinetic force of objects crashing off of each other, you must carefully figure out a solution whereby your pinballs successfully force the red block to hit the ground at the bottom of each level. A willingness for trial and error, great patience and determination are essential – You won't complete each level on your first attempt, and need to regularly re-evaluate your aiming and firing strategy.

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.
