How do I play?

• Drag a stone block from the tray at the bottom up into the 8×8 grid. The block lifts above your finger so you can see where it will land; a faint copy shows the spot, and any row or column that would clear glows gold.
• Prefer taps? Tap a block in the tray, then tap a cell on the grid. On a computer you can also hover the mouse to preview, press 1–3 to pick a block and H for a hint.
• Fill a whole row or column and it clears. Clearing two lines at once, or clearing on back-to-back moves, builds a combo — and Pebble shakes the ground.
• You get three blocks at a time; three new ones arrive once all three are placed. Blocks never rotate.

What are the goals?

• 🎯 Score — reach the points target.
• 🧱 Clear lines — clear the number of rows/columns shown.
• 💎 Gems — gems sit inside stones. Clear the row or column that holds a gem to collect it.
• 🧊 Ice — thick ice needs two clears: the first cracks it, the second melts it.
• ✨ Fill the shape — cover every glowing cell. A covered cell stays counted even if its line clears afterwards.
• 🐍 Free Noodle — Noodle the snake is stuck in a stone. Clear his row or column.
• 🪨 Survive — a crowded board and only a few pieces. Place every one of them.

Every level has a piece budget (the 🪨 number at the top). When it runs out before the goal — or nothing in the tray fits — the level is over and you can try again straight away. Every level is checked by a solver robot before it ships, so the pieces you get always allow a win.

How do I get 3 stars?

Finish the goal using as few pieces as possible. The results screen shows the level's par (the number of pieces our solver needed): par + 1 or fewer gives 3 stars, up to par + 5 gives 2, and finishing at all gives 1. Survive levels give stars for your score instead. Using more than two hints on a level costs one star.

What does the hint do?

Tap 💡 Hint and Pebble points at one spot where a tray piece fits well. It is free; it just nudges you along.

How does the Daily Board work?

• Tap the Daily Board banner on the home screen. Everyone in the world gets the same board that day.
• A new board arrives at midnight UTC (00:00 Coordinated Universal Time — it may be the evening or early morning where you live).
• Your streak goes up by one the first time you finish each day's board, and that first finish also earns one star for the rock garden. Finish on back-to-back days to keep the streak growing; miss a day and the next finish starts a new streak at 1.
• You can replay the day's board as often as you like to beat your score; only the first finish counts for the streak.
• The board is carved on your device from the date and proven by the solver before you see it. Nothing is downloaded and nothing is sent anywhere.

What are Classic and Relax?

• Classic starts with an empty board and endless pieces. Clear lines and chain combos for a high score; the run ends when nothing fits. Bigger, trickier shapes appear the longer you last.
• Relax never ends: there is no timer and no game over. Use Undo as often as you like and Swap for three fresh pieces whenever nothing fits. End the session from the pause menu whenever you feel like it.

What is the rock garden?

Stars you earn in levels (and one star per Daily Board finished) can be spent in the 🪴 rock garden on mossy stones, mushrooms, ferns, lanterns, bamboo, a bonsai, a bench and a lotus pond. Pick something from the stone shop, then tap a plot to place it. Tap a placed item to put it back — its stars are returned, and your level stars never go down.

Colour-blind patterns

Open ⚙️ Settings and switch on Colour-blind patterns: every block colour then also carries its own pattern (dots, stripes, rings, checks and so on), so pieces can be told apart without colour.

Screen shake

Pebble's earthquakes shake the screen on big clears. Switch on Calm effects in Settings to turn off the shake and most particles. The game also respects your device's reduce-motion setting.

The music or sound is off

Open ⚙️ Settings on the home screen and switch Sound effects and Music on. On iPhone, sound plays even with the silent switch on.

Does the game collect anything?

No. There are no accounts, no ads and no personal data. Stars, streaks, the garden and settings are saved on your device only. See our privacy policy.
