Slider

What the completed slider image looks like.

Slider is a classic puzzle game that involves unscrambling a shuffled up picture by moving tiles. You can do up to two slider puzzles per day and each completed puzzle grants you a 30,000 WC prize. Slider costs nothing to play and you may take as many moves as you need to complete the picture.

At the start of the puzzle you will be presented with a picture of Apollo that has been divided into 15 randomly shuffled tiles and one empty square. You move tiles by clicking on them, which will "slide" them to the currently empty square (only a tile that is adjacent to the empty square can be moved, as tiles can only be moved into the currently empty square). Underneath the tiles is a grayed out/semi-transparent image of how the picture should look when completed (visible one tile at a time through the empty square), which can be used as a guide for determining where each tile belongs.

Strategy

User Anima (ID #3506) created this excellent guide that explains how to complete slider puzzles:

Having trouble with slider? Frustrated that a great money maker is just out of your grasp? Look no further! I used to suck at slider too, but this strategy makes it easy as pie.

Here's the finished puzzle in number form.

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15

Once you have a tile in place, you shouldn't have to move it again. The strategy here is to put the tiles in position two at a time. Put tiles 01 and 02 in place first. Then put 03 and 04 into place. Then 05 and 06 in place, then 07 and 08 in place. Then put 09 and 13 into place, the 10 and 14. At this point, the last three should be easy to figure out.

Special Prize

If you are one of the first two players to complete a slider puzzle on a given day you will recieve a Soaring the Heavens Wallpaper as a bonus. Being one of the first two players is a lot about luck, but here is the basic method for at least standing a chance of getting the wallpaper (Note: a fast connection is extremely helpful).

1. Mostly finish a slider puzzle on the previous day and leave one piece out of place in a way that when you click it, it will move into the correct place and complete the game.
2. As soon as wajas time hits 12:00AM, click the piece to complete the puzzle and hope that another player didn't beat you to it.
