When playing in ranked game modes such as Duel and Teamfight you can earn MMR points and be assigned a rank. There are 6 tiers, that each have 5 ranks within.
If you do not play within 1 week, your rank icon will change to "Unranked" but your MMR value will remain the same. Playing a single match will restore your rank after the MMR value has been adjusted.
