How to play Stonezone

The goal is to clear all coloured stones from the board. When matching stones touch horizontally or vertically, they disappear.

Move the mouse pointer between two stones. The cursor shows the direction in which the stones can be swapped. Click to perform the swap immediately.

Stones can be swapped horizontally, vertically and diagonally. At the intersection between four stones you can perform a cross-swap: both diagonal pairs swap at the same time, as long as the stones in each pair can be moved.

Each swap counts as one move.

There are also special stones that can help you clear the board:

• Dynamite explodes when its timer reaches 0 and destroys all adjacent stones.
• Radioactive stones explode when clicked and destroy all adjacent stones.
• A trashcan can be used once to make one stone disappear.
• Magnets hold horizontally and vertically adjacent stones in place.
• Teleports transport stones from one location on the board to another.
• Solid rocks cannot be moved normally.

Each level has a time limit and a maximum number of moves. If your move count drops below zero, points are deducted from your score.

Level titles sometimes contain a hint. When you solve a level you receive a password. Remember it so you can continue later from where you left off.

Stonezone: gameplay statistics and privacy

We collect limited statistics to understand how difficult our levels are and to improve the game. You can play without an account.

What do we collect?

For each level attempt we record the level and version, start time, allowed and used moves, active playtime, outcome (win, timeout, reset or abandoned), and number of solution hints requested and shown. A random temporary attempt identifier links the start and end events.

What do we not collect?

These gameplay statistics contain no name, email address, IP address, persistent browser identifier, advertising ID or individual move history. We use no cookies or localStorage for these statistics, so we cannot recognise repeat players. The web server may separately retain technical access logs; these are not part of the gameplay statistics.

Purpose, legal basis and retention

We use this information only to improve level quality and assess difficulty and hint usage. We rely on legitimate interests in improving Stonezone with minimal data collection. Raw gameplay records are kept for no more than 90 days. Aggregated statistics that cannot be linked to individual attempts may be retained longer.

Privacy questions and rights

Because we do not store a persistent player ID, we cannot reliably associate an individual attempt with a person. For privacy questions, objections and personal data requests, contact the site administrator using the contact option on the Stonezone website. You can also complain to the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
