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!

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.

Forget about all that tower defending, missile launching, hoop throwing, and high-speed racing action for a while, and immerse yourself in an addicting online puzzle game that really makes you knuckle down, and think logically and creatively. Atomic Puzzle 2 is an unusual and stimulating science-based activity for young Einsteins, older kids, and brain-teaser enthusiasts of all ages where you have to eliminate all of the atoms (bright, differently colored spheres) from a complex molecular chain. Faced with a grid of colored balls connected by rubber-like links, your goal is to match & eliminate same-colored atoms (two or more) by clicking on a ‘Connector Atom’ of a different color that is linked to each of the immediate atoms you plan to remove. By taking out this Connector Atom, you cause the same-colored atoms to be pulled together, and collide, explode, and disappear! Keep repeating this process until the grid is empty.

This very interesting yet challenging problem-solving activity could be a good fit for fans of online brainteasers, chemistry-based puzzles, and molecular physics exercises in the classroom or at home with family and friends. There are very few games on the web that have such an interactive science-based premise with a dash of "match game" color and problem-solving fun thrown in for good measure! Your logical thinking skills are truly tested as you try to select the optimum connecting atom to remove in order to create a collision of same-colored atoms. The puzzles get more complex and intricate as you progress, with serious concentration, good strategic planning, dogged determination, and plenty of trial and error required. Ok Molecule Master, time to show us your scientific superpowers! Happy atom colliding!

Divide is an easy-to-play yet highly-stimulating, geometry-themed puzzle game where you must ‘divide’ a large wooden shape in order to form a target number of smaller pieces. The catch is that you have only allowed a set number of slicing actions to create a set number of independent wooden pieces, so you must be extremely precise with your shape-dividing skills. This head-scratching, problem-solving puzzle requires imagination, good analytical thinking skills and strategy. Accurate mouse control skills are also very important.

Use ‘stopping blocks’ to control the momentum of a rolling ball, and slide it into an exit portal: Road Blocks is a very challenging, maze-based visual puzzle and problem-solving brainteaser game where you must guide a white ball to a red exit portal (like a goal) in multiple, increasingly-difficult levels. The catch is that your rolling white ball can only move horizontally or vertically around the confined grid, and can only stop by impacting with a wall or other object (manually stopping the ball is impossible!).

Reasons to play this multi-level, brain teaser puzzle: Although the game has a simple concept (move a ball around a maze toward the exit), there are number of very tricky elements to it that should prove testing for even the most seasoned visual puzzle aficionados. Each level plays as an interesting problem-solving challenge where you must carefully observe the playing field, and all levels are a stern test of your ability to figure out the correct path to the exit.

Skills needed to win: The willingness for lots of trial and error is a very important part of this game – You almost certainly won't complete each level on the first attempt. Analytical thinking skills and a well-planned strategy are called on as you visualize (predict) the ideal path to the exit portal for your rolling ball. A cool head, determination and stamina also play a major part in your success.
