Just Stack · Just Play vs Giraffic Jam

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.

Giraffic Jam is a quiet logic puzzle about feeding giraffes. Each giraffe stands on a stack of hay. A taller giraffe hides every shorter one behind it, so from the edge of the board you only see some of them. The signs tell you how many. Stack the hay so that each row and each column holds every height exactly once. The first few boards are gentle. Then the signs start coming out, and you have to work the lines you still have a lot harder. EASY TO PICK UP Your first puzzle is a real board you solve yourself, with a little guidance along the way. It takes about a minute. Grids start at 3x3 and grow to 5x5. NO GUESSING Every level is checked before it ships, so reasoning alone will always get you there. When you are stuck, the answer is already on the board. HINTS THAT SHOW THEIR WORK A hint picks a square you can work out right now and lights up the sign and the line it came from. The next one is yours to find. TAKE AS LONG AS YOU LIKE No clock, no score, nothing counting down. Warm colours, soft sounds and a savanna drifting past behind the board. It all runs offline, so it is just as happy on a plane as on the sofa. WHAT IS IN THERE • Grids from 3x3 up to 5x5 • Every puzzle solvable by logic • Hints that explain themselves • A tutorial you play instead of read • Progress saves as you go • Works offline, no internet needed • No timers Read the signs. Stack the hay. The giraffes are waiting.
