"Fifteen" is a logic game, the goal of which is to put the numbers from 1 to 15 in a square box. You can only move them in one plane.
It is necessary
Fifteen
Instructions
Step 1
Shuffle the numbers in the box. In a 4 by 4 square plane, you should have fifteen numbered tiles and one empty space to move. Try not to remember what and where you moved. This will make the game really interesting to you. If you are a gambling person, then give the tags to the child for five minutes. He will carry out this task in good faith.
Step 2
Start building the first row with knuckle 1. Free the top left margin and move the unit there step by step. At this stage, it doesn't matter which knuckles will go to the bottom row and which ones to the top. Their placement will change more than once, so all attempts to fold the bottom row may fail.
Step 3
Complete the entire first row. Knuckles 1, 2, 3 and 4 should be in place. The algorithm is the same, clear the field for the dice you are interested in and, moving the numbers adjacent to it, raise the chip you need. It will be very easy to line up the first row because you have plenty of room to move around.
Step 4
Complete the second row. Knuckles 5, 6, 7 and 8 line up in exactly the same way from left to right. This is easy enough because the position of the bottom knuckles is not taken into account when making the top two rows. The path of each knuckle may be longer, because the top row is already occupied. When playing for speed, at this stage you need to calculate which path will be shorter, and how much it will affect the location of other chips.
Step 5
Place knuckles 9 and 13 in their places. Further they do not move. Use the remaining six positions for all movements. This is enough to put together the "tags".
Step 6
Move knuckles 10, 11 and 12 to their places. Do not try to line up the bottom row, as a rule, with the correct movement of knuckles 10, 11, 12, the remaining knuckles will fall into place. Sometimes it is possible that the last two tiles, 14 and 15, are reversed.
