Abstract

Skill scores represent a ranking or other indication of the skill of the player based on the outcome of the game in a gaming environment. Skills scores can be used in matching compatible players on the same team and matching opposing players or teams to obtain an evenly-matched competition. An initial skill score of a player in a new gaming environment may be based in whole or in part on the skill score of that player in another game environment. The influence that the skill scores for these other game environments may have in the skill score seeding for the new game environment may be weighted based on a defined compatibility factor with the new game environment. The compatibility factor can be determined based on a game-to-game basis, compatible categories or features, game developer defined parameters, or any combination of considerations.

Claims

1. A method implemented by a computing device, the method comprising:

receiving a first seed skill score for a first game that has previously been played by a player, the first seed skill score reflecting one or more scores by the player in the first game; and

determining an initial skill score of the player for a new game based on at least the first seed skill score of the player for the first game, wherein the new game and the first game are different games that are related by a compatibility factor reflecting compatibility between the first game and the new game.

2. The method according to claim 1, further comprising:

recording the initial skill score of the player in a storage device in association with the new game.

3. The method according to claim 1, further comprising:

determining the initial skill score as a blended skill score based on the first seed skill score and another seed skill score for another game.

4. The method according to claim 1, wherein the first seed skill score comprises a first seed average score reflecting an average score of the player in the first game and a first seed confidence level reflecting a distribution of scores by the player in the first game.

5. The method according to claim 4, wherein:

the initial skill score comprises an initial average score and an initial confidence level, and

the determining comprises determining the initial average score based on the first seed average score and determining the initial confidence level based on the first seed confidence level.

6. The method according to claim 4, wherein the first seed average score comprises a mean and the first seed confidence level comprises a variance.

7. The method according to claim 1, further comprising:

determining whether another compatibility factor reflecting compatibility between the first game and another new game is below a threshold, and

when the another compatibility factor is below the threshold, omitting the first seed skill score when determining another initial skill score for the another game.

8. The method according to claim 1, wherein the first game comprises an auto racing game title and the new game comprises a different auto racing game title.

9. The method of claim 1, wherein determining the initial skill score comprises using the compatibility factor to interpolate between a base skill score for the new game and the seed skill score.

10. A system comprising:

a seeding module configured to;

receive a first seed skill score for a first game that has previously been played by a player, the first seed skill score reflecting one or more scores by the player in the first game, and

determine an initial skill score of the player for a new game based on at least the first seed skill score of the player for the first game, wherein the new game and the first game are different games that are related by a compatibility factor reflecting compatibility between the first game and the new game; and

a processing unit of a computing device, the processing unit being configured to execute the seeding module.

11. The system according to claim 10, further comprising a storage device configured to store the initial skill score in association with the new game.

12. The system according to claim 10, wherein the first game and the new game comprise different game titles.

13. The system according to claim 10, wherein the seeding module is further configured to evaluate a set of parameters for the new game and a different set of parameters for the first game to determine the compatibility factor.

14. The system according to claim 13, wherein at least one of the set of parameters or the different set of parameters comprise developer-provided parameters.

15. A memory device or storage device comprising executable instructions which, when executed by at least one processing unit of a computing device, cause the at least one processing unit to perform acts comprising:

receiving a first seed skill score for a first electronic game that has previously been played by a player, the first seed skill score reflecting one or more scores by the player in the first electronic game; and

determining an initial skill score of the player for a new electronic game based on at least the first seed skill score of the player for the first electronic game, wherein the new electronic game and the first electronic game are different games that are related by a compatibility factor reflecting compatibility between the first electronic game and the new electronic game.

16. The memory device or storage device of claim 15, wherein determining the initial skill score comprises using the compatibility factor and the first seed skill score to adjust a base skill score for the new game and thereby obtain the initial skill score.

17. The memory device or storage device of claim 16, the acts further comprising:

updating a skill score of the player for the new electronic game based on outcomes when the player plays the new electronic game, wherein the skill score starts as the initial skill score before being updated.

18. The memory device or storage device of claim 17, the acts further comprising:

receiving, over an electronic network, an outcome of the first electronic game for the player; and

determining the first seed skill score based at least in part on the outcome.

19. The memory device or storage device of claim 18, wherein updating the skill score comprises applying a probabilistic inference algorithm to update a probabilistic distribution for the skill score.

20. The memory device or storage device of claim 19, wherein the probabilistic inference algorithm is a Bayesian inference algorithm and the probabilistic distribution is a Gaussian distribution.

21. The memory device or storage device of claim 15, wherein determining the initial skill score comprises using the compatibility factor to interpolate between a base skill score for the new game and the seed skill score.
