On chain cows and bulls tournament built on Inco network, leveraging fully homomorphic encryption to enable secret values and randomisation in smart contracts.
Commonly known as Mastermind
- A game is started and there is a secret combination of 4 pegs randomly ordered and coloured from 6 different colours.
- A player tries to guess the code by placing a sequence of 4 colored pegs.
- After each guess, the player gets feedback:
- A black peg for each correct color in the correct position (bull).
- A white peg for each correct color in the wrong position (cow).
- Objective: The player uses the feedback to deduce the secret code within 8 attempts.
-
Each player is required to deposit 0.0001 inco per game, this goes into a pot.
-
Should the player be unable to solve the puzzle within 8 attempts they forfeit their deposit.
-
If the player successfully solves the puzzle, they receive points and appear on the leaderboard
-
Points can be redeemed proportionally to the inco in the pot.
where:
- ( x ) is the withdrawable amount
- ( y ) is the users points
- ( z ) is the total points of all users
- ( v ) is the total deposits in the pot
-
If a user redeems their points they are removed from the leaderboard.
-
Points are calculated as follows
where:
- ( p ) is the points
- ( n ) is the total possible attempts (in this case, ( n = 8 ))
- ( a ) is the number of attempts needed to solve the puzzle
-
Finally, a users total points are the sum of their points from each game.
where:
- ( y ) is the sum of all game points
- ( pi ) is the points from the ( i )-th game
- ( k ) is the total number of games played
