Start a new summer
Pack up for the year and come back next summer. Your sea glass, finds and upgrades reset, but you keep your postcards and your journal, and each postcard makes everything give off 25% more.

How to play Pebble Bay
Pebble Bay is a merge game in a seaside rock pool. Find a shell or launch a boat to drop one into the first empty square. Put two of the same thing together, at the same stage, and they become the next stage: two grains of sand make a pebble, two pebbles a cockle, and so on up to a great pearl. Boats grow from a twig to a tall ship.
To merge, tap one thing and then a matching one, or drag one onto the other. With a keyboard, the arrow keys move between squares and Enter picks up and merges. Every square shows its stage number.
Everything in the pool gives off sea glass every second, and each stage gives off far more than the one before. Shells give off the most. Boats give off less, but bring visitors, so everything gives off more. A mix of both grows fastest.
The tide comes in every so often and washes up a free shell, even while you’re away. Upgrades make it come sooner, bring more shells and bring bigger ones. If the pool fills up, select something and clear its square. Once something reaches stage 9, you can start a new summer with postcards that make everything give off more, for good.
Pebble Bay is free, needs no account and saves your progress in this browser. You can back it up or move it to another device on the Save page. It is an original game made by Littleby, an independent studio.
