Zen Sort
Read full descriptionHide full description
Some puzzle games want your attention. Zen Sort just wants to keep you company. Pour little animals between glass jars until each one holds a single kind of friend. That's the whole game. There is no timer counting down, no lives to run out, and no way to lose โ only a quiet, satisfying click as the last crab settles into place. A GAME THAT NEVER RUSHES YOU โข No timers. No lives. No energy meter, ever. โข Unlimited undo, always free โ never watch an ad to fix a mistake โข Par moves are a gentle target, not a punishment โข Put it down mid-level and it waits exactly where you left it 3,000 LEVELS, EVERY ONE SOLVABLE Every single level is verified by a solver before it ships, so you will never hit an impossible board. They open gently โ four colours at first โ and grow to twelve as you find your rhythm. MEET THE SHORE FRIENDS Sort a crab, a sleepy fox, a chick, a frog, a little whale and more. Each one has its own soft voice, so you hear who is moving. Unlock a theme and the whole cast changes with it โ nocturnal creatures for Tide Night, garden visitors for Zen Garden. ONE MINDFUL SORT A DAY The Daily Calm is the same puzzle for everyone, refreshed each morning. Keep a streak if you like streaks โ and if life gets in the way, a free monthly freeze covers a missed day. No guilt built in. A SHORE THAT FILLS UP Stars wash treasures onto your beach: sea glass, a striped pebble, a message in a bottle, eventually a lighthouse. Twelve to find, all earned by playing. MADE TO BE KIND โข Colourblind-friendly โ every friend is a different shape, not just a colour โข Full VoiceOver support โข Reduced-motion setting for anyone who prefers things still โข Plays completely offline No leaderboards. No rivals. No streak-shaming. Just you, a beach, and something gentle to tidy.
Planet Merger
Read full descriptionHide full description
Drop a planet. Watch it fall, collide, and merge into something bigger. Planet Merger is a physics puzzle about building the solar system one collision at a time. When two identical planets touch, they merge into the next one up โ Pluto becomes Mercury, Mercury becomes the Moon, and on it goes. The board fills faster than you expect, the physics never quite behaves, and one well-placed drop can set off a chain reaction that clears half the screen. MERGE ALL THE WAY TO THE SUN Eleven worlds to discover, from tiny Pluto to the Sun itself. Every collision is driven by real physics, so no two games ever stack up the same way. Cross the line at the top and it's over โ so think about where each one lands. LEARN SOMETHING REAL Every planet you unlock opens a card of genuine astronomy: diameter, distance from the Sun, number of moons, day length, year length, surface temperature. Plus the details that stick with you โ like the fact that it rains diamonds on Neptune. 220 PLANET PUZZLES A separate quiz mode with 220 questions about the solar system, space exploration, and the science behind it all. Ten questions a round. ONE TAP TO PLAY Tap where you want the planet to fall. That's the entire control scheme. Easy to start in a spare minute, hard to stop when you're one merge away from a world you've never seen. PLAY IN YOUR LANGUAGE Fully translated into 9 languages, quiz questions included. Free to play. An optional one-time purchase removes ads permanently.
