Yushino is a CrossWord game with Numbers!

Here is a quick guide on how to play:
Quick start
Place numbers left-to-right or top-to-bottom to create “number sequences” just like you create words in CrossWord games.
To build a number sequence:
If the sequence has three or more numbers
Every number is the sum of the previous two.
When you add the two previous numbers you only look at the last digit.
For example, 684 is a valid sequence because 6 + 8 = 14 and the last digit of 14 is 4. Other examples are 7630, 954932, etc.
If the sequence has two numbers
The numbers must differ by 1. For example: 56, 87, 21, 90, etc. Note that 90 and 09 are valid two number sequences.
Placement
In the first move you must place a tile in the central (yellow) square. Each new move must touch an existing sequence on the board. It can either extend a sequence or “cross” one or more sequences, or both!
Scoring
You score points for every number placed (7 points for a 7, 4 points for a 4 and so on) and your points are multiplied by the “multiplier” squares.
2* and 3* multiply the tile on them by 2 or 3 respectively.
2X and 3X multiply the whole sequence\non them by 2 or 3 respectively.
The multiplier squares are valid only the first time they are used.
Yushino for all 7 tiles
If you use all 7 tiles in one move you get 100 bonus points!

Enjoy Yushino!
