Levels 1-5 are free. Levels 6-30 need a $3 licence key. About the full pack
Driftquartz is a sliding gem puzzle that loads as an ordinary web page. There is no app to download and no plug-in: the game is a few small files that run in your browser, on a desktop or a phone. Your progress is saved in that browser only, so it stays on your device.
On a keyboard, use the arrow keys or W A S D, Z to undo and R to restart. On a touch screen, swipe on the board or tap the direction buttons.
Level 1 with the shortest solution marked: the dashed line is the route and each number shows where that slide ends.
The sliding rule
One move is one slide. The piece keeps going until a wall or the board edge is in its way, so the skill is choosing walls to stop against. It collects each gem it crosses. The exit only opens once every gem is collected; before that the piece passes over it without stopping.
What it needs to run
A current web browser with JavaScript switched on, and nothing else. There is no account to create and no email to give. Every file the game uses comes from this site: it loads no ad network, no analytics script and no code from other sites, and it sets no cookies. The only time the game talks to a server after the page has loaded is when you enter a licence key for the full pack.
Level 1, move by move
Level 1 is a 5 by 5 board with three walls and one gem. Counting rows from the top and columns from the left, the piece starts in row 5, column 1; the gem is in row 2, column 5; the exit is in row 4, column 5.
- Slide right: the piece moves four cells and stops at the edge of the board.
- Slide up: the piece moves three cells, picks up the gem and stops against a wall. On the way it slides straight over the exit, which was still shut. The exit is now open.
- Slide down: the piece moves two cells and is caught by the open exit.
That is three moves, the par for level 1: the computer search found no shorter solution.
What is free and what costs $3
