Most sorting puzzles ask you to pour coloured liquid between bottles. Sand Drop changes the material completely: every level is a pixel-art picture made out of coloured sand, and your job is to release that sand colour by colour until every grain lands in the bucket it belongs to. The first pictures are gentle and teach you the idea in seconds, but a moving loop underneath the board keeps you honest. Pour without thinking and the whole board backs up, so this is a calm game that still punishes careless moves.

## Gameplay
You release colours by tapping them, or you drag a finger through the picture to open a channel for the sand to flow down. The freed sand drops through a funnel onto a moving loop, then flows on into colour-coded buckets below. Each bucket shows how many grains it still needs, and it only clears once it receives exactly the right colour. The loop itself has a fill meter, and if too much sand piles up at once you run out of room and the level stalls. That one rule turns a relaxing toy into a genuine planning puzzle, because the order in which you release colours matters as much as the colours themselves. Later pictures pack the colours tighter together, so one wrong release can bury the colour you needed next, and you have to think two or three moves ahead before you tap anything.

## Features
Every level brings a new pixel-art image to sort, so the board never looks the same twice. The physics are the star of the show: grains pour, slide and drain in a way that feels satisfying to watch, and the smooth motion plus calm visuals give the game a relaxing, almost ASMR feel. Play is one-finger and unhurried, which makes it a good fit for short breaks, and the difficulty rises gradually, rewarding patience and planning rather than quick reflexes. It is a sorting game first and foremost, but the sandy twist keeps it fresh for players who have already played plenty of water-sorting games.

## Controls
Everything is done with taps and drags. Tap a colour to drop it, drag to cut a path through the sand, and that is all there is to learn. There are no buttons to memorise and no fast reactions required, so you can pick the game up in seconds and play it one-handed while you have a few minutes to spare.

## Pros and Cons
On the plus side, the sandy twist feels genuinely different from other sorting games, the pace is relaxing rather than stressful, every level has a clear goal, and the game is easy to learn while still getting tricky in later stages. On the downside, the slow and deliberate pace will not suit players who want fast action, a careless pour can force you to restart a level, and the core loop stays the same from level to level, so variety comes from the pictures themselves rather than from new mechanics.
