Utilize the effects of gravity, and strategically transform blocks in order to rid the game screen of all purple characters! Playable on Android and iOS mobile phone, tablet, laptop, notebook and desktop PC, Transforming Blockies is a fun, physics, gravity and timing-based puzzle (for elementary school age kids, middle & high school students) where you must use the special transformative power of each shape character to logically alter the game environment in order to eliminate all purple shapes from the platform-based levels. Some colored shapes change from round to block-like and vice versa, while others double in size when you click or tap on them. You must cleverly use these transformation actions to your advantage in each of the 40 increasingly-difficult levels. Remember: Eliminating the purple characters is your goal, and if you accidentally get rid of other colors, you fail the level!

This online, multi-level, HTML5-based, physics-based engineering 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. Skills required include fast and tactful reactions as some levels require multiple transformations in quick succession. An appreciation for the effects of physics is also needed as you must use gravity to get shapes moving in many cases. Good old trial and error determination, common-sense logic, sharp analytical thinking, and creative engineering skills also come into play as you attempt to alter the game environment successfully in all 40 levels.

Utilize your imagination, freehand-drawn creations and the effects of gravity to push and channel a small red ball into the light-blue basket in the 50 increasingly-difficult levels! Some levels require the drawing of a simple one-line bridge or pathway, while other levels need much more complex drawings in order to propel or deflect the ball towards the U-shaped goal.

This HTML5-based, interactive, multi-level problem-solving brain teaser and construction puzzle game should work on Android devices as well as most web browsers for PC / Mac. To play with full screen, you may have to turn your device horizontally. Skills required include high levels of concentration, good hand-eye coordination, simple drawing ability, logic-based problem solving skills, analytical thinking and creative engineering skills, and a general appreciation of the basic laws of physics and gravity. Good patience is rewarded here, while dogged determination and a willingness for trial and error are essential traits of a real problem solver. This is especially true in later levels when you must create large webs of bridge and pathway drawings.

Tip: Don't waste too much time trying to make a busted drawing work out. When needed, simply click or tap on the circular arrow at the top of the play area to start over from scratch. A fresh mind can do great things on a clean slate!

Lever Physics is a challenging, math, physics and equilibrium-based game for upper elementary school / middle school students, high school teens and grownups where you must place and balance weights (fun items and characters) on a ‘seesaw-style’ beam connected to the ground by a pivot (fulcrum). Playing against the clock, you must place any available weights onto the lever (beam), and try to keep it perfectly balanced in the middle.

Some quick physics revision: A lever is a simple mechanical device which consists of a beam or stick or rod, and helps to lift weights with less effort. To be effective (as a lever), it must have a support to pivot on. This pivot is called a fulcrum. Levers can then be used to exert a large force over a small distance at one end of a structure by exerting only a small force over a greater distance at the other end of the same structure (beam). (Physics teachers - Brief correction welcome here if needed..!)

The Law of Equilibrium: A lever is in equilibrium when "the load" and "the effort" balance each other. The effort (weight) multiplied by its distance from the fulcrum = the load (weight) multiplied by its distance from the fulcrum. This law of equilibrium is true for all classes of levers.

For example, 2 pounds of effort exerted 4 feet from the fulcrum will balance 8 pounds located 1 foot on the other side of fulcrum. This effort times (multiplied by) distance about the fulcrum is the "Torque" (rotational force).

Back to Lever Physics Flash game!: Don't be fooled by the fun and playful imagery in this load balancing brain-teaser! It is a tricky, analytical thinking puzzle and logic problem solving challenge that requires good observation skills and hard thinking combined with mathematical and engineering solutions.

This interactive, point-and-click activity allows some trial and error (by quickly placing, removing and re-positioning weights) but you definitely cannot delay your decisions for long as the clock is ticking fast! Ok Balancing Master, can you ‘lever’ yourself to the top of the class?

Play this Game

Quad Cop is a really cute, eccentric and challenging interactive physics-based game for older kids & teens on PC / desktop where you must feed hungry cartoon sheriff characters in order to force them into special actions that knock bandito outlaw characters off and out of the game screen area.

These quirky sheriff characters have the ability to roll down hills, fly around the game screen, and create impactful explosions – but only after you feed them specific types of spicy food!

This interesting and clever problem-solving puzzle requires good visual and analytical thinking skills, a fun and creative streak, smart timing, and a cool head with lots of patience when under pressure. Some basic knowledge of the effects of gravity and motion is also important as you try to gauge the exact moment to feed your hero character! Enjoy the wacky action!
