Sand Loop is a relaxing sand sort puzzle: a finished sand artwork is sitting in front of you, and your job is to collect every grain of it. Guide the buckets along the conveyor, pour each color into the one that matches, and let real sand physics do the rest. Take the whole picture apart, color by color, until the board is clear. Relax and unwind after a long day, or take one level at a time on the go. How to play: - Tap to release a bucket and send it down the conveyor - Each color of sand gets poured into the bucket that matches - Work through the artwork until every grain is collected - Place your buckets strategically to solve the puzzle - Clear the board and enjoy the payoff Easy to pick up, genuinely tricky by level 100! Why you'll love it: The sweet spot between a brain teaser and a stress-relief game. Simple taps, beautiful results, steady progress, sand physics and ASMR-style sounds that make every level worth watching. Game features: - A sand sort puzzle built on a loop: timing matters, not just matching - Real sand physics: every grain pours, piles and settles - Hundreds of handcrafted levels, with more in every update - Fresh obstacles and twists that keep changing how you solve - A different sand artwork to take apart in every level - Soft ASMR-style sand sounds and a calm, colorful art style - Free to play, with no countdown timer on any level - Limited-time events to take part in when you feel competitive It never settles into one trick. Just as you get comfortable, a level changes the rules on you - a new obstacle, a new way the sand behaves, a new reason the order you pour in suddenly matters. There is a fresh twist every couple of weeks, so the game you are playing in a month is not the one you downloaded. Hundreds of levels in, it is still finding ways to surprise you. Take a moment for yourself. Let the sand flow. Download Sand Loop for free and start sorting.

There is no light in here. The maze is drawn only by the sounds you make. Tap, and a pulse spreads out from you — walls flare where it touches them, then fade back into the dark. Hold, and a low hum shows you further, and costs you more. Throw a distracting stone, and listen to where it lands. Everything that hunts you hears exactly the same sounds. That is the whole game. Sound is how you see, and it is how you are found. Every sound spends breath, and breath does not always come back. The player who lights the maze up cannot get out of it; the player who creeps through in near-silence can. SEVENTY HAND-BUILT LEVELS, in seven sets that each teach you something new: • Origins — learning to see with sound • Echoes — things that hunt, and things on rails • Hollows — crossings over what is not there • Thresholds — closed doors need a key to open them • Spiral — rings and spokes, not corridors • Honeycomb — six ways on from everywhere • The Famous — mazes that exist, or did, or never did! THE FAMOUS ONES ARE REAL, MOSTLY. Hampton Court, Bridge End Gardens, Horta, Versailles and Schönbrunn are traced from their published plans: the same hedges and the same wrong turns, in the dark. Villa Pisani and Ashcombe are reconstructions built on what is documented of them. Chartres is the pattern rather than the floor. Hawara is gone, so it is built from what Herodotus wrote down. And the Minotaur's is ours, because his never existed! Every one of them says on screen which it is. A MAZE A DAY. Everyone in the world gets the same daily maze, built from the date. Clear it on consecutive days to build a streak. The daily is free, always, and it draws on everything the paid sets contain — doors, rings, honeycombs — so you can see what the rest of the game is like before deciding whether you want it. AN ENDLESS DESCENT. Deeper and darker, without end. Your breath carries from one depth to the next, so how far you get is decided by how much sound you were willing to spend twenty levels ago. THREE LEADERBOARDS through Game Center: today's maze by fastest time, resetting every day; the longest daily streak you have ever run; and the deepest anyone has gone. THINGS THAT HUNT. Three of them, and they are not the same. One is blind and wanders towards noise. One waits, silent, for you to come to it. One runs a fixed route and does not care about you at all — until it does. ALSO: a relic hidden in every level, awards for finding half of them and then all of them, colour themes that unlock as you go, and a full tutorial, because almost nothing here can be worked out by poking at it. FREE TO PLAY, AND HONEST ABOUT IT. Thirty levels and the daily maze are free forever. One payment unlocks everything else — the later sets, the famous mazes, the endless descent. It is a single purchase, not a subscription. There are no adverts anywhere in this game, no tracking, and no analytics. Play with headphones if you can. It is a game about listening.
