## What is Yushino?

Yushino is a crossword game with numbers.
Easy to learn, easy to play - but epic battles are sure to ensue when you try to beat your friends at it!

## Yushino is simple

You create number sequences on the board, from left-to-right or from top-to-bottom. Every sequence must conform to one of the two rules:

## First rule:

If the sequence has 3 or more numbers, every number is the sum of the previous two numbers - but we only use the last digit of the sum. For example, if the previous two numbers are 6 and 7 then since 6 + 7 = 13 the next number must be 3 (we ignore the first digit, "1"). Other valid Yushino sequences are 875, since 8 + 7 =(1)5; 7291, as 7 + 2 = 9 and 2 + 9 = (1)1, etc.

## Second rule:

If the sequence has 2 numbers, the numbers must differ by 1 - but keep in mind that the numbers repeat, so we go from 0 to 9 and then back to 0 again, which means that 9 is next to 8 but it is also next to 0. Examples of valid two-number sequences are: 56, 87, 90, 09, 98, etc.

## Do I have to count all these?

Not really! The score is calculated on the fly as you place the numbers on the board and it will be shown over the last number you placed, inside the score bubble
The bubble only shows up if the move you have placed is valid. But be aware:
the first two numbers that you place may not be valid by themselves, but the third number you place might make them valid! For example, if you place [5 2], then the sequence is not valid by itself yet, because 5 and 2 differ by 3 instead of by 1 (according to the second rule). But, if you then place 7, you will have [5 2 7] which is a valid sequence according to the first rule, since 5 + 2 = 7.
In that case the score bubble will not show up until you place the 7.

## How do I start a game?

Play with a Facebook friend, choose a random opponent, invite a friend by email or Yushino username, or pass the phone (or tablet) and play with a friend.

Create a Yushino sequence on the board by placing tiles vertically or horizontally. The very first sequence must touch the central square:
Subsequent sequences must connect to previously played sequences

You might want to try the Coach. She's going to tell you how good your sequence is - and she won't rat on you either!

You can exchange your numbers if you don't like them, but you will lose a turn. You cannot exchange numbers in two consecutive turns or if there are less than 7 numbers left.

But maybe before you exchange numbers you might want to check what's left in the bag.

While you're waiting for their move, chat your friend up; who knows, maybe it breaks their concentration!

Or start another game - hey, it's free!

All your current games are listed in your main screen. First the games where it is your turn to play, then the ones where it is your friends' turn. If your notifications are enabled in your phone's settings, we will send you a notification when it's your turn to play.

If your friends are taking too long to play you can send them a reminder.

## How many numbers in the bag?

This is the distribution of tiles when the game starts:

You can find out at any time how many numbers are left using the "numbers left" button

## The highest score wins!

For each sequence you create you add the score for each number.

The score for each number is the number itself (so an 8 scores an 8 and a 0 scores a 0) and blanks score 0 points regardless of what number you make them to be.
You get a 100 extra points if you play all 7 tiles in one move!
Play sequences on the colored squares on the board to get bonus points.
Doubles the number     Triples the number
Doubles the sequence    Triples the sequence
Try combining more than one bonus squares to get your numbers multiplied more than once.
The game ends when you play all your numbers or when you or your friend
use "pass" 3 times in a row.
If you use up your numbers first, you get the numbers in your friend's rack added to your final score, and your friend has them subtracted from their score!

## More tips

Numbers can be placed so that multiple new sequences are formed simultaneously using neighboring numbers. You'll score points for each new sequence created during a turn!

You can end a game early if it's your turn by tapping "Resign"
If it's not your turn and your friend stops playing the game - even after you've reminded them repeatedly! - they will be resigned automatically after some time.
