About this place ↓About Lake Yoa, Lakes of Ounianga
The Lakes of Ounianga in northern Chad are a chain of 18 lakes in the middle of the Sahara, in one of the driest places on Earth. They are fed by water that fell as rain thousands of years ago and now flows underground. Lake Yoa, the largest, is saltier than the sea, and its red and green colours come from tiny algae and bacteria, while some smaller lakes nearby are fresh. The lakes are a UNESCO World Heritage site. This photo shows Lake Yoa, with palm trees and grass along its shore and sandy desert beyond.
Puzzle tip: start with the green and red water near the shore, then the palms and grass, and the desert and the sky last.

Moving pieces: Drag a piece with your mouse or finger. With a mouse you can also click a piece once to pick it up — it follows the pointer until you click again to set it down.
Joining pieces: Drop a piece near its matching neighbour and it snaps into place with a click. Joined pieces move together as one group. There’s no fixed spot to build in — assemble anywhere on the table.
Play As: Pick how many pieces to cut the picture into, from 12 up to 300. Switch on Hard shape at the bottom of the menu for trickier pieces with three knobs on every side. Changing either setting starts the puzzle over.
Table: At the very bottom of Play As, choose what you build on: leather, light oak, green felt or charcoal. Your choice is remembered for every puzzle and doesn’t restart the one you’re on. Light oak table photo by simon on Unsplash.
Pause: Click the timer, or the pause button next to it. The table is covered while paused so nobody can sneak a look; click it (or the timer) to carry on.
Show picture: The picture button shows the finished image as a guide. Click it again to hide it.
Arrange pieces: Lines up all loose pieces in tidy rows at the sides of the table, handy for spotting edges or a missing piece. Click again to scatter them. Pieces you’ve already joined stay exactly where you left them.
Restart: Mixes up the pieces and starts again with the same settings.
Fullscreen: The last button on the bar gives the puzzle the whole screen. Press it again or Esc to leave.
Progress: In the middle of the bar, the counter shows how many pieces are joined, and the percentage shows how much of the picture is done.
Finishing: When the last piece clicks in, the timer stops at your finishing time, and you can play again or try another puzzle at the same size and shape.
