Master Block Balancers urgently required: 18 increasingly difficult block-stacking levels available for those who love physics-based, block building / balancing games. Old Constructor is a stimulating Tetris-style construction and balancing game of pencil drawing graphics style, and similar in theme to the Perfect Balance game series. Set against a nostalgic black and white background, you have to create a solid, stable tower structure using a set of differently-shaped blocks in each level. The order of the blocks or the appearance of your structure is entirely up to you. The key thing to remember is that all shapes in each level must be added – no matter what the order or sequence.

This challenging puzzle game requires a basic understanding of the laws of gravity, logical thinking, creative engineering skills (especially as you gauge which shapes would better suit the foundation layers of the structure, and which would be more appropriate for the higher layers and top of your construction). Patience and determination are essential virtues here. Happy tower building!

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.

Send a block home with smart block removals, shrewd strategic planning, and tactful mouse-clicking! Go Home Block 3 is a physics-based, problem-solving puzzle game for kids and teens where you must interact with the play area using your mouse, and cleverly remove obstacles in order to guide a hairy blue block to a wooden ‘Home / Exit Door’. Unfortunately, your block character cannot move of its own accord, and therefore needs your interaction skills to make its journey homeward. Featuring 20 increasingly-difficult levels, you must overcome a range of platform and ledge-based obstacles and hindrances in this ‘escape-the-level’ brain teaser challenge.

Skills required: Fast reaction and mouse-clicking skills are needed, with an emphasis on timing and pinpoint accuracy. Analytical thinking skills must be combined with focus, concentration, stamina, and determination. Some later levels require deep thought and strategy.

You control the button; you control the outcome! Blockoomz 2015 is a highly interactive, challenging and explosive physics and reactions-based puzzle game. Here, you must utilize smart strategy, excellent timing and smooth mouse control to blast ‘bad guy’ pink, black and grey bombs off of the game screen while simultaneously protecting the ‘good guy’ yellow bombs from harm. As Chief Bomb Expert, you must carefully decide when and where to execute each explosion.

This highly-stimulating, point-and-click arcade game requires very good analytical problem solving and creative engineering skills as you attempt to generate sufficient momentum and interaction to knock some bombs off and out of the play area. Levels are filled with platform-style hindrances as well as bombs positioned in awkward places, so a certain amount of learning through good-old trial and error is essential. A basic understanding of the effects of physics on a "suddenly disorderly environment" is also important – For example, bombs are certain to be flying through the air!

Now, let’s see how well you remain cool, calm and collected under intense pressure in this tricky, incendiary challenge!

Strikey's Revenge is a challenging, "street golf"-themed, physics-based puzzle game where you must shoot a golf ball into a waste basket in a series of 18 progressively-difficult, obstacle-filled levels (which play like a wacky game of mini golf combined with the intricate science of power, angle, and trajectory!). You play the role of Strikey, a fiery golfing prodigy, and must use his incredible skills and aiming devices to figure out the best way to engineer a solution that deflects the ball into the urban waste basket (bin) in each tricky level.

Skills required in this multilevel golf, aiming and accuracy game: Creative engineering and analytical thinking skills are very important in this environment – There are multiple ways to get the ball into the basket depending on the angle and power used in your shots. Trial and error is also part of a smart strategy as you test out how the ball reacts against the various obstacles and unusual objects in each level. Good observation skills, a steady hand, a cool head under pressure, and expert mouse control all play a part in your chances of success.
