Store description excerpt
Vial Sort takes a familiar idea — pour colors between vials until each one matches — and builds it with real care underneath. Every level is generated from a solved board and shuffled backward through legal moves, so it's guaranteed solvable before it ever reaches your screen, not just probably solvable like a random deal. Difficulty isn't a guess here, either. A search algorithm calculates the true shortest solution for every level and sorts it into one of four tiers — Easy, Medium, Hard, Expert — with measured average solutions of roughly 11, 17, 22, and 26 moves. Stuck partway through? The same solver finds your next best move in real time and highlights the two vials involved. It points. It never pours for you. Inside the vials • An endless, procedurally generated ladder of levels, each one verified solvable, not guessed at • Four honestly measured difficulty tiers, graded by an actual solving algorithm, not by color count • Unlimited undo, plus a real-time hint that shows the move without making it for you • A colorblind mode with ten distinct symbols on every vial, not just brighter colors • A dead end explained the moment it happens, with one tap back to your last move or a clean restart No countdowns, no lives to lose, no daily caps — pour through as many or as few levels as a queue, a commute, or a quiet evening gives you. Progress saves after every single move, so closing the app mid-pour never costs you anything. Vial Sort runs entirely on your device. No account, no tracking, no data collected — it works fully offline from your very first pour to your last level.
