Store description excerpt
Clear your mind. Fill the grid. Gridfulness is Sudoku for two kinds of days. Some days you want quiet: no flashing ads, no timer ticking unless you want one, no streaks to guilt you — just you, the grid, and a moment to breathe. Other days you want a real challenge: a puzzle that pushes back and makes you earn every number. Gridfulness is built for both, in the same calm, uncluttered app. Whether you have two minutes or twenty, Gridfulness meets you where you are. Play at your own pace. A CALMER SUDOKU • No internet connection needed, play anywhere, anytime • Clock-free by default — the timer is hidden unless you choose to show it • Sightlines gently guide your eye along rows, columns, and boxes, so you focus on solving instead of scanning • Calming light and dark themes — pick the palette that soothes you and helps you focus • Smooth, tactile input that feels effortless — use a traditional number pad or the long-press rosetta menu for an even more minimalist experience • Free hints not only show you the next step, they help you understand why • No penalty for setting a puzzle aside — a gentle moment of calm waits for you whenever you finish SERIOUS DEPTH, WHEN YOU WANT IT • Unlock the hardest difficulty — a hidden final tier that searches up to 30 seconds to hand you the toughest grid it can generate • Our grids are difficulty-rated using a method comparable to Hodoku, one of the reference tools serious solvers already trust. • Stuck on a hard grid? The hint system doesn't just fill a cell — it names and explains the technique, from Naked and Hidden Singles, through X-Wings and Skyscrapers, all the way up to Swordfish, Finned and Sashimi Fish, XY-Chains, ALS-XZ, Forcing Chains and many more • Every grid has exactly one logical solution — never a guess, no matter how hard it gets • For the serious solvers, our difficulty tiers show what techniques are required on the settings screen and map to the following Hodoku scores on average: ~310, ~475, ~730, ~1060, ~1265, ~2960. The final tier will hunt for the hardest grid it can find in 30 seconds, be warned it will often generate grids far exceeding the previous tier BUILT TO HELP YOU FOCUS Sudoku is a proven way to quiet a busy mind — and a proven way to sharpen it as brain training. The rules are simple, the logic is absorbing, and there's nothing quite like that satisfying click when the last number falls into place, whether it took thirty seconds or thirty minutes of chain-hunting. Gridfulness strips away the pressure, so the puzzle becomes a place to rest or a place to push yourself — whichever you need today. PLAY YOUR WAY • Designed for iPhone and iPad, portrait and landscape orientations • A full range of difficulty, from a relaxed warm-up to a genuinely elite challenge • Use the smart keypad with pen, pencil and eraser mode, or turn it off and use the rosetta input for a truly minimalist experience • Play against the clock, or hide it to remove distractions • Every theme supports a lig
