Stackopolis is a fun and infuriating blocks stacking game puzzle that will test your hand-eye coordination speed like no other! The game initially seems super-simple but is actually terribly tricky! Some say, it’s the most addicting game since Tetris – Once you start playing, it’s Game Over for everything else! The goal is to recreate the “ARTIST'S IMPRESSION” (which you can see on the right hand side of the game screen) by rearranging the blocks. The “BLUEPRINT” (in the center of the game screen) tells you exactly how many blocks need to go where. You’re up against the clock! You only have 60 seconds. Time’s ticking, so get clicking!

A cool and challenging spot-the-differences puzzle game for eagle-eyed sleuths! Tales of Pylea: Crux is a very tricky, online visual puzzle where you must find and eliminate 4 differences between two seemingly identical side-by-side picture images in each level. Based on the fantasy webcomic ‘Tales of Pylea’, this is certainly no walk in the park – the 4 differences between the comic strip images in each level are absolutely minute.

Reasons to play this fun, interactive difference-finding game: Stimulate and exercise your observation, focus, concentration, patience and perseverance skills as you work hard to pick out the often innocuous differences between the two pictures. Can you find the differences quicker than your friends or family members can? Perhaps create a fun contest!

Strategy to win: Simply, focus and find! Of course, keen eyesight is required to scrutinize every inch of each image. As you are looking at an online comic strip, there may be numerous different panels in each level – so you're concentration levels need to be optimal. Use thought-out processes such as pinpointing smaller areas of each comic strip – and focus on that area for a little while (Don't worry; there's no time limit here).

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 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.

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.
