Play a hard, multi-level, sliding tile brain teaser game where you must strategically ‘create a channel’ for a ball to pass from the left hand side of the maze to the target / Goal area. Rolling Ball is a visual problem-solving, escape-style game and construction puzzle (for elementary & middle school age kids, high school teens & adults) where you must slide and rotate tiles / blocks around a confined game grid in order to engineer a pathway to move a steel ball from one side of the grid to the red ‘GOAL’ block on the opposite side. 

In each of the 60 increasingly-difficult levels, your task is to ‘unscramble’ the maze, shuffle blocks around the grid, and get the ball to the Goal area in as few ‘moves’ as possible. This is made all the more difficult because sometimes there are some trick tiles (additional channel pieces) that you don't need for that level, while sometimes blocks need to be rotated (90 degrees at a time) in order to transform them into a usable block for your channel building plans. 

This online, HTML5-based, sliding & rotating block puzzle game should work on iOS and Android devices as well as most web browsers for PC / Mac. Key problem-solving skills required here include a combination of high levels of concentration, good analytical thinking and logic skills, creative engineering and strategic planning, patience, determination, stamina and resilience to keep working towards a solution when the going seems very tough. A willingness for trial and error is important because the mazes become extremely complex as you progress further and further up the game levels.

Keep your ball out of harm's way by timing each ‘jump’ to perfection in order to keep it away from the fast-moving jaws of the gateways. This is a repeat-play challenge where your goal is to beat your top score with each new attempt (You score one point for each gate you pass through).

Play one of the most phenomenally popular word scramble puzzles of all time on your mobile phone, tablet, notebook, laptop, or desktop PC! 4 Pics 1 Word Online is a highly-stimulating, multi-level and head-scratching, scrambled brain teaser game inspired by the legendary app where you are shown four pictures that are linked by one word (which you must then guess from the set of jumbled up letters at the bottom of the play area). Play on your own, or enlist the help of other puzzle activity enthusiasts in your family, classroom, or group of friends! See how far you can climb up the famous 4 Pics 1 Word scoreboard – each completed puzzle moves you to the next level.

Game Concept: Each level follows the same format - You are shown four completely different images, and must figure out the single word that links all four pictures. The scrambled letters of this word are displayed at the bottom of the game screen. The catch here is that there are also some trick letters in the set that are NOT part of your target word.

Example Level: For example, the four pictures might be: 1) Railroad tracks, 2) A person in a gym, 3) A teacher with a student, 4) A boy talking sternly to his dog. The answer that links all four pictures: TRAIN!
 
This online, HTML5-based, picture-based, word scramble game should work on iOS and Android devices as well as most web browsers for PC / Mac. Skills required include good analytical thinking and cognitive thinking skills, logic, a decent vocabulary range, and simple spelling skills (The level is only completed once you type in the target word spelled 100% correctly). High levels of concentration and patience are also very important. Ask for help from a best friend or family member if you get stuck on a word! You may even want to turn the game into a multiplayer activity!

Play an online, multi-level, pirate-themed, match 3 puzzle game with a wide variety of level types on your mobile phone, tablet, notebook, laptop, or desktop PC! Pirates: The Match-3 is a challenging, multi-level matching grid puzzle game for kids, teens and treasure-loving adults where each level has a very specific task. Examples include levels where you must reach a specific points target, levels where you must eliminate a set number of colored gemstones, levels where you must clear blockades from the game grid, and many more! 

While your tasks change from level to level, the general "match three" gameplay remains the same; you must swap gems and other treasures around the grid in order to create matching groups of three or more adjacent pieces in a row either horizontally or vertically. Some levels are played against the clock, while in others, you are hindered by a limited number of moves!

This online, HTML5-based, match 3 brain teaser game has 50 levels, and should work on iOS and Android devices as well as most web browsers for PC / Mac. While a sense of urgency and sharp reactions are important for competing against the clock, good strategic planning and visual problem-solving skills are the key attributes required here. 

Cluttered game grids often require smart analytical thinking and creative engineering tweaks in order to create a solution where you can form matching groups more easily. Patience, high concentration, and a willingness for trial and error all come into play, especially in later levels when the grids are larger and more complex.  

Controls: Simply click or tap on the gemstone you want to move, and swipe to swap it with an adjacent gem. If this swapping move results in the creation of a matching group of 3 or more, great! If your swap is invalid (i.e. it doesn’t create a matching group), nothing happens until you go again.

Playable on your mobile phone, tablet, notebook, laptop, or desktop PC, you must try to keep your knight out of harm's way by avoiding spiky obstacles, and defeating the skeleton baddies wielding your knight's sword.

Spaceship Landing is a challenging arcade-style skill game with a straight-forward concept. You play the role of a spacecraft pilot who must land safely onto all Green platforms that appear in each level (Normally two, and landing on the 1st Green platform frees up the 2nd Green platform by changing its color from Blue to green). However, your spaceship is quite fragile, and you must use the rocket-propelled action of the ship to very deftly land without excessive impact. You must also keep your eye on your fuel gauge, and re-fuel on the Red platforms in order to avoid a loss of control.

Completing levels wildly at high speed may not be the best course of action, as you must always be aware of your quite limited fuel stocks.

Play an interactive, sliding tile puzzle game with 100 levels on your mobile phone, tablet, notebook, laptop, or desktop PC! Car Parking is a challenging problem-solving, strategy brain teaser game (for elementary school kids, where you must use your car as a tool to strategically push large boxes around a confined, maze-like parking lot. Featuring a simple top-down view and board-style layout, you must methodically move the crates into position on specific parking spots marked with a ‘P’. This can prove tricky as the boxes can only be pushed forward (one move / step at a time), and each of the 100 levels takes place in a very small car park where space is limited and your moves must be carefully planned.

This difficult, online, HTML5-based, strategy / problem-solving puzzle game should work on iOS and Android devices as well as most web browsers for PC / Mac. To play the game with full screen, you may have to turn your device horizontally. Each mini maze puzzle requires a combination of logical and analytical thinking skills, strategic planning, step-by-step analysis, and the ability to think outside the box – Pun intended! Patience, determination, and high levels of concentration are really important here. A willingness for trial and error is also key – You can restart levels as often as you like, and there are no time restrictions.

Tip: Move slowly in measured actions, with one arrow key click or one tap touch per move (Do not make very quick clicking or tapping actions as the game sometimes does not accept such moves as valid). When the crate is successfully accepted into its placement, it turns red in color. If the box does not turn red in its final placement, it means that the game software has not accepted your overly-swift movement into that parking position.

Play a fun matching pairs game for kids, with a problem-solving twist; Instead of matching pairs of identical tiles, here, you must match tiles with their ‘opposites’! Playable on your mobile phone, tablet, notebook, laptop, or desktop PC, Opposites Attract is a multi-level matching game where you must clear a Mahjong solitaire-style grid against the clock by matching quirky picture tiles with their ‘opposite image’.

Complete 50 increasingly-challenging levels by completely clearing the grid before the clock reaches zero!

This online, HTML5-based, matching pairs / puzzle game should work on iOS and Android devices as well as most web browsers for PC / Mac. To play the game with full screen, you may have to turn your device horizontally. Unlike regular matching games where you simply pick out identical tiles, here you must use your common sense and logical problem-solving skills to make quick deductions about opposites. Some examples are pretty simple – such as a happy face emoji VS a sad face emoji. Others require a bit more analytical reasoning, such as the pairing of a tortoise and a hare (slow VS fast). As each level is against the clock, fast reactions also come into play. This is especially true in later levels when the grid is larger and your time limit is shorter.

Tips: If you are stuck, try the ‘Hint’ button for a helpful push in the right direction. If there are no available matches remaining, click or tap on the ‘Shuffle’ button to jumble the tiles around. Each time you use the Shuffle feature, 300 points are deducted from your overall total score!
