Extremely Hard Puzzle Game / Brain Teaser - Gridlock

Rating: 8.6/10 - 26 votes

For those who love to grind out solutions to what may appear complex visual and structural puzzles: Gridlock is an extremely hard, multilevel, sliding block-based puzzle game and highly-stimulating, brainteaser activity for older kids, youth and grownups!

In each of the 40 increasingly-difficult levels of this really tough visual problem-solving challenge, you must unlock the puzzle, and find a way to slide the blue block through the opening on the right hand side of the confined playing grid. The catch is that each individual block can only be moved either vertically or horizontally. The solution is achieved using careful thought and methodical maneuvering of the other slide-able blocks that populate the small play area.

Skills / strategy required: Creative engineering and analytical thinking skills are very important in this tricky maze-like escape game. Each level has the same concept and purpose, but all 40 levels require very sharp focus, concentration and deep thought, and provide a stern examination and exercise of your visual problem solving ability.

Great patience and determination are also required - You need a strong temperament to intricately plan and visualize each move toward each solution, and go high into the Gridlock levels. Accept trial and error as an important ally in your quest – You very likely won't complete each level with ease, and must learn from your mistakes in order to progress (so good memory skills sure come in handy!).

How to Play: A very tricky, Flash-based, sliding tile / brainteaser puzzle game for notebook, laptop and desktop PC / Mac (with certain browsers). In each of the 40 progressively-challenging levels, your task is to slide the blue-colored block out through the opening on the right hand side of the play area.

Using your computer mouse or touchpad, Left Click and drag blocks (either vertically or horizontally) into empty spaces around the grid. Maneuver blocks around the play area, and try to ‘free up’ the blue block. When you slide the blue block out of the game area, you automatically progress to the next level. If you get stuck, click on the ‘Reset’ button at the bottom of the game screen to reset the grid.
