How many free hextech chests have you earned this year?

I was just wondering how many hextech chests people have earned, and on what champions, since its release earlier this year. Ive gotten 21 of them so far.

Sona, Leona, Lulu, Nami, Vi, Lux, Annie, Taric, Nautilus, Viegar, Sivir, Blitzcrank, Jhin, Ashe, Janna, Orianna, Garen, Evelynn, Karma, Gnar, and Nocturne

Chests I could have had chests for the S ranks, but I didn't own the champions ;~; (OFA, Nemesis draft games.) Yorick, Ziggs, Quinn and Urgot.
