# Pairing methods

These are the algorithms that power our matching. The descriptions below leave a lot of complexity out and we aim to provide a general understanding here.

{% hint style="warning" %}
Our algorithm has been carefully designed and have a level of complexity under the hood. 

There are a great many functions designed to handle edge cases and give a result from mathematical computations of all possible matches, and all possible combinations of those matches.

### Best with Best

This methodology is self explanatory. This is the fundamental algorithm that is best used when first seeding a farm. It has the highest probability to make printers by pairing the best with the best match of highest gene score. This will establish a strong basis for your gene pool as you are expanding the farm.

### Best Average

This methodology is used to spread the quality genes you created with the Best/Best algorithm. The idea is that now that you have a few printers, instead of breeding them together this method will find matches that have the highest probability of purifying Axies in your farm so that you have a strong left skewed bell curve for farm gene purity therefore creating longevity for your Axie investment. An intensity of 1 will be very close to best with best, while a score of 5-10 will be more like highest scored matches of best with average or worst genetic scored Axies.<br>
