Calling all young science game aficionados! Would you be interested in a challenging little physics-based puzzle? If so, Moony Boom is a highly interactive online science-based game for kids where you have to strategically add objects, create pathways, and build bridges to divert a falling moon toward an exit point at the bottom in each level.

A basic understanding of physics and gravity is very useful as you try to gauge in which direction the cute personified moon is going to travel. Let’s see what you can ‘add’ to this challenging puzzle! Happy problem solving!

E-Depth Angel is a challenging spot-the-differences puzzle game where you must find and eliminate 5 tiny differences between two side-by-side comic strip pages in each level. Based on the popular Japanese sci-fi action manga webcomic ‘E-Depth Angel’, this is a tricky visual puzzle for older for kids & teens where you need to be on alert for the smallest discrepancy between the two images.

Strategy to win: Naturally, good observation and concentration skills are essential here.

Here, instead of making a row of 4 counters like in classic Four in a Row / Captain'’s Mistress games, you must try to outmaneuver your opponent and create square-shaped groups of 4 same-colored gemstones.

Strategy to win: Good players of tactical puzzle games know that you must strike a strategic balance between attacking and defensive play. You must also remain constantly aware of your opponent's moves and likely immediate plans. Blocking your opponent's path to a group of 4 could be just as valuable as creating your own group. This game also lends itself to ‘front runners’ – so if you manage to get yourself ahead, keep the pressure on!
