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.
