A mindful, relaxing puzzle game with 99 increasingly challenging, handcrafted levels. Simple to play but not so simple to complete! Immerse yourself in the soothing ambient soundtrack and focus on solving the grid. “Quite simply one of the most beautiful puzzle games I have ever played. The design is simple, yet aesthetically pleasing, and the soundtrack is a wonderful sonic wash that perfectly compliments the gameplay. The puzzles themselves are well pitched. The introductory rounds are small enough to lend themselves to both a studied approach or random tapping. They gradually ramp up the difficulty level, and with so many to work through, there is great value for money to be had." - an App Store customer from the UK. How to play: Start at the origin and tap the squares to light a path across the grid. There’s just one rule! The numbers scattered across the grid tell you how many squares you must light up around each one to solve the puzzle… and that’s where the skill comes in!

Atomas is back with a fresh take and a bunch of new gameplay mechanics. Easy to learn but full of depth, it’s the perfect game for passing time on your commute, while waiting in line, or whenever you have a few minutes to spare. Start with hydrogen and fuse atoms together as you work your way up to the final and mythical element, Omnium, said by neo alchemists to have the power to create any molecule ever imagined. As you play, you unlock and equip up to three tools by reaching new high scores. Use them to get out of tricky situations or to set up smarter, more strategic moves. As you progress through the elements, you enter atomic realms where you can choose between three permanent effects that stay with you for the rest of your run, and with the right combination, your score can grow exponentially. New special atoms like the Swapper, Amplifier and the Glitch add more variety and open up new strategic possibilities. Molecular chains act as score multipliers, letting you push your score higher and higher. With all these systems working together, every run feels different and offers a fresh challenge. Become a neo-alchemist and create the legendary element Omnium.
