Just Stack · Just Play vs Islands Hashi

Just Stack is a quiet take on the sort puzzle — colored wooden blocks scattered across small open-top boxes. Pour the top of one box onto another. One color per box wins the level. Three small rules govern the whole game: 1. Tap a box to lift its top group; tap another box to pour. 2. The block at the bottom of the pour must match the color it lands on, unless the target box is empty. 3. Sort every box to a single color — or leave it empty — to win. That's it. The rules are small. The space they open up is not. WHAT'S INSIDE — 700 hand-rated puzzles in total, across seven difficulty tiers from gentle Beginner to honest Expert. — Campaign mode: 200 levels with a steady difficulty curve. Early levels go quickly so you find your footing; later ones stretch out for long evenings. After every win, one tap takes you to the next level. — Finish the 200? Free Play unlocks. Pick any difficulty and keep drawing from the remaining 500-puzzle library. — Played a puzzle? You won't see it again in the same tier until you've worked through it. PART OF JUST PLAY Just Stack is the fourth game in the Just Play series, after Just Sudoku, Just Puzzle, and Just Yin Yang. The series shares a single design philosophy: classic logic puzzles, rebuilt patiently, in a quiet voice. No ads, no streaks, no engagement loops. The interface stays out of the way; the puzzle does the talking. Each game looks the same on day one as it does on day one hundred. Just Stack uses the same calligraphy-paper background as Just Yin Yang, but trades black-and-white stones for deep walnut boxes holding low-saturation blocks — indigo, mustard, plum, dark green, and others. If you enjoy this one, you may also enjoy its siblings. PLAY YOUR WAY — Tap to lift, tap again to pour. No dragging needed. — Three undos per level for the moments you didn't quite plan ahead. — Restart the current level any time — never costs you anything. — No moves left? A small message tells you so. No silent stuck states. — Soft haptics that confirm your touch without shouting. PRIVACY BY DEFAULT Just Stack does not collect any personal data.

Hashi is the bridge-building logic puzzle also known as Hashiwokakero — pure deduction, no luck, no clutter. Draw bridges between numbered islands until the whole map connects into one network. Simple to learn, deeply satisfying to master. A grid of numbered islands floats on a quiet sea. The number on each island tells you exactly how many bridges must touch it. Connect them all so that every island is linked into a single network — with no crossing bridges and no diagonals. Every puzzle has one logical solution, and you can always reason your way to it. HOW TO PLAY • Drag from an island to build a bridge; drag again for a double. • Tap a bridge to remove it. • Each island's number = the bridges touching it. • Bridges run straight, never cross, never go diagonal. • Win when every island connects into one group. A WORLD OF ISLANDS Sail through 34 real-world archipelagos — the Florida Keys, the Hawaiian Islands, the Aegean, the Galápagos, the Faroes, the Whitsundays, Raja Ampat, Svalbard and more — each with its own handcrafted puzzles and a few words about the place. PUZZLES WITH A SHAPE Fifteen Shapes collections cut the board into a silhouette — a heart, a star, an anchor, a boat, a key, a crescent, a wave. The same rules, with a picture waiting at the end.
