Strategic Thinking / Logic Skills Game - Open Doors

Rating: 7.4/10 - 81 votes

Test and exercise your visual problem-solving skills with 25 blueprint-style mazes that may look simple but prove to be extremely tricky - where swinging doors that govern each maze make reaching your destination a tough task! Open Doors is a highly-challenging, multi-level, maze and strategy-based puzzle game where you must guide a movable square to an X-shaped Exit Portal. However, each maze is filled with ‘doors’ that swing open and closed depending on which way your square hero moves. This means that each of the 25 increasingly-difficult levels presents its own mini door-opening brain teaser – and it's your job to figure out the solution that ensures the square reaches the end point!

Skills required: This quirky, interactive, visual puzzle game requires high levels of focus and concentration - especially in later levels when the brain teasing action is more complex. Smart analytical thinking, creative engineering, determined problem solving, and general multi-tasking skills all come into play as you carefully plan your route through the alternating door openings. The ability to mentally zoom out and see the ‘bigger picture’ is also very helpful.

How to Play: A Flash-based, maze / puzzle game for notebook, laptop and desktop PC / Mac (with certain browsers). In each of the 25 progressively-challenging levels, your task is to guide the large white square to the X-shaped Exit Portal. Use the Arrow Keys on your computer keyboard to control the movement of your square, and press your R Key to reset the level at any stage.

Each maze is filled with hinged doors that swing open and closed depending on the direction your square moves in. Your square can push a door open by moving toward the door (if the hinge allows this). Your square can also force a door to move 90 degrees into a different / closed position by moving AWAY from the door in the direction of the swinging hinge. In later levels, some of your movements will cause one door to move one direction and a neighboring door to move another. Can you figure out each required sequence to gain access to the X-shaped Exit Portal?
