Use ‘stopping blocks’ to control the momentum of a rolling ball, and slide it into an exit portal: Road Blocks is a very challenging, maze-based visual puzzle and problem-solving brainteaser game where you must guide a white ball to a red exit portal (like a goal) in multiple, increasingly-difficult levels.

Reasons to play this multi-level, brain teaser puzzle: Although the game has a simple concept (move a ball around a maze toward the exit), there are number of very tricky elements to it that should prove testing for even the most seasoned visual puzzle aficionados. Each level plays as an interesting problem-solving challenge where you must carefully observe the playing field, and all levels are a stern test of your ability to figure out the correct path to the exit.

Skills needed to win: The willingness for lots of trial and error is a very important part of this game – You almost certainly won't complete each level on the first attempt.

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.

Would you please help a cute, gooey slime ball to activate and reach an exit portal? Sling is a tricky, physics-based platformer and game of skill where you control the acrobatic movement of an elastic, ‘sling-able’ green slime ball. In each of the 50 increasingly-challenging levels, you must fling this friendly slime ball character (called Sling) to multiple ‘ledge grabs’ in order to open a ‘Vortex’ which you can then escape from! However, many of the ‘grabs’ are in awkward to reach places, and are obscured or blocked by obstacles.

Skills / strategy required: This challenging, interactive, multilevel skill game requires good hand-eye coordination, analytical thinking skills combined with keen problem solving determination, lots of trial and error as well as the ability to judge angles and trajectory (The curve or path followed by a flying projectile or by any object moving under the action of some force).

‘Slinging’ the green slime ball accurately can be a tricky task but the action here is very similar to the firing of cannons or archery shooting in many online aiming & accuracy-based games. A good strategy is to first plan out your route around the level – Then pinpoint the ‘grabs’ you want to reach first, and sling away!

Play an excellent, old-school board game challenge comprising 16 separate puzzles - easy, medium, hard and extremely difficult: Solo really is a fun yet challenging, 1-player, logic-based visual puzzler (for young kids through adults and seniors) that follows the rules of Peg Solitaire (also called Solo Noble and BrainVita) – a classic jumping board game similar in concept to Chinese Checkers.

Skills / strategy required: Peg solitaire games are difficult problem-solving brain teaser puzzles where sharp logic and analytical thinking skills are required to find out a solution. Complete focus and concentration, great determination and stamina are essential here – You really need to be ‘in the zone’ to solve the Solo puzzles, especially in later levels.

This really is a teamwork-style challenge where you must toggle between the different visions – and use the diverse attributes and features of each viewpoint to your advantage.

Skills required: In this tricky, atmospheric and thought-provoking platformer, your problem-solving skills are regularly tested in each level. You must use a combination of analytical and logical thinking to methodically figure out the best way to advance your alien through the level, and collect the parts needed to repair his spaceship.
