ick on settings button (on menu it's bottom right) choose "The annoying Tutorial Mode". It can help, but you can always turn it off. Sometimes you need to know sth about the puzzles, click the Manual button (it's bottom left)

In settings you can check out credits, variables hide/show the mouse, change volume to music, etc.

GAMEPLAY TUTORIAL:

LEVEL 1

Click on InfoScreen (top right in the game), it tells you the code for 3-digit and 4-digit.

For example: 2-7-4-1-3-6-8 (every time it comes up in a different colour)

This means on the puzzle on the right click "2" then "7" then "4".

The puzzle on the left (with an arrow rotating) click on digits: "1", "3", "6" "8". Got something wrong in this puzzle? Got the "1-4-6-8"? No worries! Click "3" and after that "8" (by clicking "8" the safe thinks there are 4 digits and submits your code)

After that... ROTATE! See that puzzle above the 2nd? While there's a mouse on it, it keeps rotating. Continue rotating until it brings you to another level.

LEVEL 2

A Simon Says task and some switch buttons.

Simon Says: repeat after left panel by clicking buttons on the right one. Once the counter turns to "Tick", you solved this puzzle!

Switchers: It's also a code e. g. 1-0-1.

At the begining those switchers are: 0-0-0

You see? The 2nd one is '0' which the same as in the code. It will light in white. That means it's set correct. Now click on first switcher, your code will be '1-0-0' and it will also light up. Click on the 3rd switcher, and your code is correct!

1-0-1

1-0-1

And... it brings you to the 3rd level!

LEVEL 3

To me it seems the easiest puzzles. Click on the small circle. It'll rotate. Continue doing so until the letters are same in both big and small circle. The big circle will change, so you need to do it again until your letters are same 3 times in a row! It brings you to the MONEY (which will get more beautiful :)
