Online Turnz Game is a brain teaser puzzle game that not only develops your logical thinking skills, but guarantees you hours of fun as well. Your aim is to help the purple guy “BLOB” to reach the finish by rotating his world. The BLOB, as well as the BLUB (who does not have to get to the finish) moves around only when you turn the game screen. A rock does not move and has no other effect other than just being there as an obstacle. A breakable rock gets destroyed after one hit. There is also a teleport block. Place two or more of these on the screen.

If you place more than two of these, they will each teleport to the next one (3 teleport blocks: 1 teleports to 2, 3 to 3 and 2 to 1). The bomb block explodes after a set time. It can be set by the person who creates the level. The death block resets the game when a player’s block hits it. You will also encounter locks with the same color keys. If the blue key is hit, the blue lock becomes passable, however, if after that the yellow key is hit, the blue block and its key become visible again and the yellow one becomes invisible. The BLOBS can enter the purple doors and the BLUBS – the green ones.

Protect the vulnerable! Shield a poor old defenselessness cow from invading alien missile-fire in this interactive puzzler by carefully dropping large blocks within the game zone! Protect The Cow: Level Pack is a top physics-based game and problem solving puzzle for older kids and teens where you must methodically drop blocks into the game environment in order to create a protective shield for a happy-go-lucky cow inhabiting land that is suddenly under attack from a naughty missile-firing alien! As soon as you make your final block-dropping effort, the alien spaceship swoops onto the screen, and fires a deluge of cannonball missiles over the area around this innocent farmyard animal.

This quirky and challenging brain teaser requires very good observation of the terrain, savvy creative engineering skills, and a highly determined problem solving attitude. You need to quickly figure out the ‘lay of the land’, and then systematically add defensive barriers that provide durable cover for your cow (For example, this might include building makeshift bridges, closing off pathways, and even propelling the cow to other areas using the powerful, descending blocks). Your alien opponent can prove quite adept at exposing the weak points in your makeshift defensive structures, so lots of trial and error, and patience play an important role in your attempts to protect your cow. Are you ready to create and construct makeshift fixes to solve each puzzle level?

Alien Bottle Buccaneer 2 is a very tricky aiming and accuracy-based shooting game and fun puzzler for kids and teens where you play the role of a bottle-smashing alien pirate. In a series of 20 highly-challenging levels, you must accurately shoot bouncy rubber balls in order to blast all of the green bottles in the confined, ledge filled environment. While the premise of the game (break all bottles before your ammo runs out) is simple, actually completing the tasks can prove extremely difficult as there are numerous obstacles and angle-based problems to solve!

Reasons to play this addicting, shooting skill challenge: This funny game requires much more analytical thinking and strategy than the average shooting game, and presents a physics-based problem solving challenge as you have to figure out the optimum angle and trajectory to smash each bottle.

Strategy to win: Trial and error forms a big part of your strategy here. While you have a decent ammunition stock of 25 bouncy rubber balls to smash maybe 5 or 6 bottles with, it's highly unlikely that you'll break them all in one shot. This means that you’ll need to perform ‘test shots’ where you see how your balls (bullets) react when fired off at certain angles. Accurate mouse control and a steady hand are vitally important here. Some levels feature very awkwardly positioned bottles that can only be reached by firing from three or four different angles.
