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. The catch is that your rolling white ball can only move horizontally or vertically around the confined grid, and can only stop by impacting with a wall or other object (manually stopping the ball is impossible!).

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. Analytical thinking skills and a well-planned strategy are called on as you visualize (predict) the ideal path to the exit portal for your rolling ball. A cool head, determination and stamina also play a major part in your success.

Play a hard, interactive, visual brain teaser puzzle, and exercise your analytical thinking skills, problem solving determination, and more! Exorbis 2 is a highly-stimulating, sliding tile-based, puzzle game for older kids, teens, college students and adults with a massive 100 levels. Here, you must use good spatial awareness skills, strategy and creative engineering ability to slide orbs onto color-coordinated ‘nodes’ in as few moves as possible. And, if all of that isn't sufficiently challenging, there's even a cool ‘editor’ mode where you can create your own levels!

Reasons to play this tough, online problem-solving game: Exorbis 2 provides a stern exercise and test of your cognitive and analytical thinking skills. The difficulty level increases sharply as you progress, making this a very rewarding examination of your puzzle busting credentials!

Your concentration and stamina levels must be sharp, and the willingness for trial and error is very important. Mostly there is only one solution to a level, so you need to learn from your mistakes, and exhaust all possibilities.

Staking Claims is a fun and addicting, 1 and 2 player visual puzzle and turn-based strategy game for kids and teens which follows the classic ‘join-the-dots or Boxes game’-style concept. In Staking Claims, you claim ownership of a square grid by creating (drawing) the final wall in a box area. Staking Claims features a cool wild west / gold rush theme where you score extra points for completing boxes with gold bars in them. Play versus a cunning computer opponent (1 Player mode) or play against a friend, classmate or family member (2 Player mode).

Reasons to play this interactive, turn-based, brain teaser game: This is a clever and creative re-imagination of ‘Dots’ – the fun doodling game famously played on copybooks for generations across the world. Staking Claims offers a good exercise and test of your focus, observation skills, analytical thinking, creative engineering and strategy skills, and more.

Strategy to win: Unlike many puzzle games, this is actually a very tactical one-on-one battle of wits often shaped around what your opponent will do – and whether you can force him/her into a mistake. There is no time limit to rush you along, so try to be patient in creating your lines. Focus hard on the playing field. Play with the ‘bigger picture’ in mind; you may have to sustain the loss of one or two boxes if it means larger gains later in the game.

Use good strategy, shrewd problem-solving skills and fast reactions to trap monsters in a warehouse full of sliding crate-like blocks (called bricks)! Monster Containment is a highly-stimulating and challenging, online interactive brain teaser puzzle game for 1 and 2 players (elementary / middle school kids, high school students through adults) to play where you must quickly and methodically move silver crates around a confined warehouse grid in order to contain and trap an increasing number of colorful little monsters. Go on a solo monster trapping run, or use good teamwork with a best friend, family member at home or classmate in a two-player mode.

Reasons to play this addicting, sliding tile-based arcade game: Monster Containment plays as an excellent test and exercise of a range of your physical and mental attributes. Focus, sharp observation skills, fast reflexes, and keyboard control skills must be combined with smart analytical thinking know-how, creative thinking skills, and determination. Showcase your talent as a lone problem-solving whizz, or unleash the power of savvy teamwork by embarking on an epic Monster Containment campaign with a partner.

Strategy to win: Although you must completely immobilize all monsters in order to progress, limiting the space they can move in is the initial key toward success. You'll find it very difficult chasing multiple monsters around the whole grid, so try to close them off in smaller corners first. Trapping more than one monster at a time can also be very beneficial, especially in later levels.

Play an addicting and challenging brain-teaser, disc swapping and matching-based puzzle game online! Bunch is a stimulating, interactive, multilevel, visual puzzle game for kids and teens that combines color coordination skills, observation skills and problem solving determination.

Read the introductory instructions to the mode you play. Depending on the mode, you might have to be more aggressive and quick in your swapping and matching. You need to focus hard on the environment, searching for possible swaps and matches. This game requires great stamina and determination to progress high into the levels.

Featuring 24 progressively-difficult challenges that require plenty of thought and smart strategy, you must carefully leap from platform to platform, discover invisible objects, use teleport devices to your advantage, combine the skills of the mirror-image characters, and more!

Strategy / skills required: Utilize fast reactions, good observation and memory skills, a cool head, sharp analytical thinking and creative engineering to find a solution to each tricky puzzle level. Some levels feature invisible ledges that you can only view for a split second, so your perception and picture memory skills really need to be accurate.

Strikey's Revenge is a challenging, "street golf"-themed, physics-based puzzle game where you must shoot a golf ball into a waste basket in a series of 18 progressively-difficult, obstacle-filled levels (which play like a wacky game of mini golf combined with the intricate science of power, angle, and trajectory!). You play the role of Strikey, a fiery golfing prodigy, and must use his incredible skills and aiming devices to figure out the best way to engineer a solution that deflects the ball into the urban waste basket (bin) in each tricky level.

Skills required in this multilevel golf, aiming and accuracy game: Creative engineering and analytical thinking skills are very important in this environment – There are multiple ways to get the ball into the basket depending on the angle and power used in your shots.

Skills / strategy required: In this absorbing, card-based matching game and visual puzzle, good concentration skills and smart decision making are very important; you must make key decisions about which cards to remove from the main grid, and when. You have a 10-minute time limit, so you can afford to be thoughtful with your decisions.

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!).

Play this Game

Reclaym is an innovative, interactive teamwork and brainteaser-style platform game for older kids / teens where you must guide a bear made of clay through a series of side-scrolling, obstacle-based levels. The soft, malleable composition of your jumping bear hero character means that he can perform specialized tasks such as flipping switches or opening doors that allow him to progress.

Background info: You play the role of the former ruler of ‘Claytonia’. Having been ousted by the evil Lord Claymore, you must find the remaining pieces of yourself by progressing through the various traps and obstacle-filled levels laid out by Lord Claymore.

Skills required: In this challenging, thought-provoking Flash game, problem-solving determination and decision making skills are really important.

This innovative feature transforms the game into a tricky, problem-solving puzzle.

Skills / strategy required: This stimulating, online brain-teaser and visual puzzle offers a very stern exercise and test of your focus, concentration, patience, hand-eye coordination, keyboard control, determination and stamina.

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).

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 this Game

The aim of the game in Solo is to reduce the number of circular pegs to just 1 solo remaining peg (Pegs are eliminated when ‘jumped over’ by other pegs – exactly the same as you would capture an opponent's piece in checkers). Solo features 16 increasingly-tricky mini-games (levels) with more pegs and fewer available grid spaces as you progress.

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.
