Ready for a fun, rope-cutting physics and skill-based game? Boom Balloon is a tricky, interactive mouse-clicking puzzle game to really get your "spikes" into. Here, you must pop three helium-filled balloons in each level by successfully manipulating the game environment, and carefully freeing and guiding the balloons toward a set of spikes! You play the role of the ‘game-changer’, and have to meticulously plan out a sequence of actions and reactions in each level that results in all three balloons being mercilessly popped (no matter how cute the balloon designs are, they’ve simply got to go if you want to progress).

Each level requires careful analysis, logical thinking, good strategy, great patience and determination to figure out the correct course of actions that will result in the balloons’ demise. Once you are ready to set your cunning plan in motion, well-timed swipes of your computer mouse, and fast reaction skills are essential. Beginners beware – later levels feature extremely complex step-by-step solutions that can only be achieved through rigorous trial and error. We hope your enthusiasm for problem-solving doesn't take flight - Remember that only the balloons need to get ‘deflated’ here! Challenging yourself is what it's all about:) Good luck and enjoy!

From the cracked parchment-style look of the play area, to the cool background noises mimicking a 15th century Italian city, this is one of the quirkiest puzzles you’re ever likely any time soon. As in all physics-based puzzle games, your observation skills, problem solving and strategic planning abilities, determination, stamina and patience are sternly exercised and tested. Be inspired by the true genius that was Leonardo Da Vinci (1452 – 1519) who even made detailed outlines of helicopter-like flying machines, tanks, and even robots in his spare time – hundreds of years before these machines were actually invented. Happy innovation!

Roll up for a tricky, absorbing, head-scratching dice-based puzzle game based on a cunningly straight-forward concept! Endice is an addicting sliding-tile brain teaser challenge where you have to maneuver sets of sliding dice (classic board game-style die) into designated outline zones in each level.

The overall ability to step back momentarily, to review and see the bigger picture, and then react urgently is essential here as it is in many real life situations everyday. Now, are you ready to take on this electrifying task?
