Interactive Online Physics Puzzle Game - Sleepy Heads

Rating: 6.5/10 - 463 votes

Sleepy Heads is a fun yet hard physics-based puzzle game for older kids and teens, and certainly not for real-life sleepyheads, where you must strategically add wooden objects to the game environment, and hope that your additions and placements cause a chain reaction that upends some happily snoozing characters! You must jolt "block-heads" from their sleepy state by interacting with the game screen and adding the wooden blocks to tip the sleepers off of their perch. Utilize the effect of gravity to ensure your cleverly placed pieces help to directly knock the dozing gentlemen off of their ledges, or push other objects chaotically around the play area so that the sleepers cannot get any decent rest!

Skills required: This highly interactive, multi-level brain teaser requires a good combination of analytical and logical thinking skills, strategic planning, anticipation skills, accurate mouse clicking, and determination. General knowledge of the pulling effects of the force of gravity is important as you try to predict where the ledges and wooden beams might move to when you make your additions. Trial and error is really key; you must learn from your mistakes, and make improving adjustments accordingly.

How to Play: A Flash-based, physics problem-solving puzzle game for notebook, laptop and desktop PC / Mac (with certain browsers). When the game loads, click the Yellow Arrow, and then select the ‘Local Save’ option. In each of the 30 increasingly-difficult levels, your task is to wake the sleepyhead characters by moving / knocking them off of their ledges. To do this, you must craftily add special wooden blocks to the game environment, and hope this initiates a ‘chain reaction’ that causes the sleepy guys to jolt awake.

Use your computer mouse or touchpad to add the wooden blocks to the play area. Note that your additional blocks can only be attached to other wooden objects that are already in position. For example, you cannot just click to add a block above a character's head. In some levels, you have to add more than one block. Once all available blocks have been added, the effects of gravity take hold. If you successfully wake all characters in that level, you progress to the next. If unsuccessful, press the R Key on your keyboard or the available icon to re-play the level. Ask a family member or best friend to add their brain power to the task if you get stuck on a level. Enjoy the physics challenge!
