The aim of the game is to find the kept hidden items in the correct order as soon as possible and collect daily points.Let s explain the MP game with an example based on numbers..
When a game starts android picks a hidden 3-digits number.
Let this hidden number be 792.
The digits of hidden number is represented by "*" character.
("***" for our sample) It has an important rule for that number.
The hidden number is selected such that a digit can occur at most once (like 123 or 754 or 912 etc..) There are no repeating digits at the number ***.When enter our first estimated numbers (sample 123) .
it seems "123 1-".
"1-" means , *** number has one digit of our estimated numbers.
But number is at different position.
(2 for our sample) Our 2nd number is 456.
After that there is no + or - positions because *** number has no our digits..Our 3rd number is 789.
After that it seems "789 1+1-" It means *** have 2 digits of guess.
One of them at same position and one of them at different position.Our 4th number is 782.
After that it seems "782 2+" It means *** have 2 digits of guess and 2 of them are same position.Our 5th number is 792.
After that it seems "792 3+" It means *** have 3 digits of our guess and 3 of them are same position.
So?
