Pandemic Simulator - In this online strategy game you play the role of an evil bug trying to cripple the worlld. Choose to be either e a virus, a parasite or bacteria with specific characteristics which in turn infects all inhabitants on Earth. You win the game by wiping out all the humans on earth. This is not an easy task as governments and hospitals are, at the same time, working hard to prevent the spread of disease and find a cure. Gain DNA points as your bug becomes more determined and spreads, then use these points to upgrade the bug.

It’s your job to infect everyone in the world with your disease. You start with a disease that's very low on the radar which looks like a locally-spread flu. This game will develop your sense of spreading a bug, and it is up to you to improve your bug and allow it to spread rapidly. Use your points wisely to maximise the pandemic's effectiveness.

Are you suited to becoming a Demolition Expert? Dynamite Blast 2 is a challenging destruction-based puzzle game where you must blow things up by carefully placing sticks of dynamite onto various structures (bridges, towers, buildings) in order to bring them crashing to the ground, below a specified height. Throughout the 35 increasingly-difficult levels, your job is to ensure that your explosives are positioned in such a way as to create MAXIMUM carnage to get you below the target "success" line.

This fun and stimulating skill-based game requires more subtlety than simply pressing the detonator button and hoping for the best. Here, you must utilize smart strategy to decide on weak points in each structure. A basic understanding of physics and the effects of gravity is helpful as you try to ensure that the falling structures are kept as low as possible. Trial and error also comes into play as you attempt to learn from your mistakes! Let’s get to the detonating action!

The physics-based puzzle genre features some of the most innovative and challenging games on the Learn4Good site. Rolling Tires 2 fits right into this inventive category – It’s a clever, strategy-based ‘block removal’ game for older kids where you have to carefully eliminate wooden blocks from a cluttered game screen in order to create a channel that will move a new "tire" (a full wheel here) to a waiting truck. While your only action is to remove blocks, you have to think hard about the specific order in which to remove them, how falling items might react to and change the environment around them, and how best to propel the wheel toward the truck.

This original, interactive and highly-stimulating brain teaser activity should be a good fit for avid science game fans, or anyone who enjoys a tricky problem solving challenge that really puts your mind to the test. Good analytical skills and a strategic brain are vitally important attributes required here as you have to think 2 or 3 moves (clicks) ahead in order to ensure your wheel has a possible pathway to reach the truck. Be prepared for plenty of trial and error too – some higher levels require you to really break things down, step-by-step. OK Puzzle Master, it’s time to show off some of that creative engineering talent! Can you find a solution to each puzzle? If you need help, ask a family member, friend or your classroom buddies to work with you as a problem solving team. Good teamwork makes a Big Difference in solving difficult problems. Enjoy!

Are you a ‘well-balanced’ person with a love of stimulating and challenging games? Ball Balance is a straight-forward, physics-based skill game for kids where you have to score points by successfully balancing a series of weighted balls on a specially-designed, ball-carrying scale. The scale has 5 different dropping areas to the left and right of the fulcrum (the gravitational center of the structure), and you have to make sure it doesn’t tip over; Do this by loading each side with an equal weight of balls. As well as keeping the scale in a carefully-balanced equilibrium, you must also try to score points by positioning three same-colored balls in a row, horizontally or vertically.

This unusual ball balancing activity is a good choice for exercising your multi-tasking skills. An understanding of the law of gravity as well as good concentration are extremely important here. One slight mistake, and the whole structure could topple over! Quick reactions also come into play, with different colored and weighted balls coming thick and fast as you progress further into the game. Your status as a Skill Game Superstar is hanging in the balance - it’s time to show who is a true master of balance!

Create chain reactions in this difficult physics-based brain teaser puzzle. Screw The Nut 3 is a wonderful example of a visual and interactive skill-based game where you have to carefully study the environment in each level, and then find an innovative solution by uniting two pieces of normal, everyday hardware (a hexagonal nut and a bolt). You must use your creative engineering skills to remove blocks, manipulate objects, and generally alter the game environment to your advantage (hopefully!).

Unlike previous versions of Screw The Nut, this Flash game takes place underwater – which means that you can also enlist the support of an array of fun-loving sea creatures to help you toward your goal of joining the nut and bolt together. Screw The Nut 3 requires concentration, logical thinking, determined problem solving skills, the ability to predict the movement and reactions of various items, and the willingness to learn by trial and error. The underwater environment adds a challenging gravity-based element to the mix as you take the floating nature of various objects into account. Right then – It’s time to crack this particular nut for good!
