Renewable Energy Engineering Game - Out Of Wind

Rating: 7.1/10 - 1089 votes

Are you a fan of construction, engineering or physics-based puzzles, or renewable energy themed-games? If so, we need your help! The environmentally-friendly villagers of Windsville have a rather tricky problem; the windmills that they use to power their town currently aren’t receiving sufficient wind to produce enough electricity! Now, the desperate residents are crying out for a problem solving whizz kid to get their windmills working by designing a unique underground gear system – and that’s where your expertise is needed! Out Of Wind is a challenging brain teaser puzzle game for middle school / high school students where you have to carefully position circular wooden gears on underground pins in order to construct a gear system that switches the main windmill back on to generate power. The catch is that the gears are often different sizes, and the pins are awkwardly positioned so that only the precisely accurate combination of gears and the correct direction of the system alignment will get things moving!

This is a really enjoyable and innovative problem solving game where an added dash of creative engineering goes a long way. You need to call on your analytical and methodical thinking skills to figure out the correct grouping of gears in each level. Simply throwing the gears onto the underground pins in a flash won’t get the job done; you must try to technically envisage the mechanism, step-by-step, all the way to the surface gear. This should prove a popular activity with young puzzle solving enthusiasts out there, or anyone with an early interest in building, structural engineering, mechanisms, and generally ‘how things work’. The people of Windsville are counting on you – it’s time to get your brain in gear!

How to Play: In each of the 20 increasingly challenging levels, your goal is to design a working underground gear mechanism that activates the windmill connected to the original gear closest to the surface. Each level has at least one ‘starter gear’ that is already moving, and your job is to add other gears to the mechanism to ensure the whole design moves smoothly from starter gear to surface gear. The circular gears available to you are located in the tab on the left of the game screen. Using your computer mouse or touchpad, simply click and drag a gear to one of the black underground ‘pins’ to add it to the mechanism. Once the gears are all moving correctly and the windmill begins to turn, you progress to the next level.

In later levels, the controls become a little more complex. For example; you may have to ‘create your own gears’ by clicking and dragging from a pin. In this instance, you can only create a set number of gears depending on a ‘forge allowance’ (e.g. your ‘allowance’ might be 9, so you can make one gear of size 6, and one of size 3 etc). There are also pools of water and lava in later levels that you have to avoid. Each time a new feature is introduced, a helpful tutorial explains the controls needed to utilize the tool. If you get stuck, click on the circular arrow in the top left corner of the game screen to restart the level.
