On the August 8 broadcast of Mnet's 'Queendom Puzzle', 7 out of 21 contestants were eliminated during a fierce semi-final round, while 14 contestants earned a chance to move onto the finals.

[SPOILERS AHEAD]

First, H1-KEY's Riina, Woo!ah!'s Wooyeon, Shiroma Miru, Kei, Cherry Bullet's Jiwon, Weeekly's Soojin, Rocket Punch's Suyoon performed "PUZZLIN'", captivating the audience with a lovely charm on stage. 

Second, Dohwa, Fye, PURPLE KISS's Yuki, Weki Meki's Elly, Cosmic Girls's Yeoreum, Yeeun, and H1-KEY's Hwiseo performed the charismatic dance number, "i DGA".

Finally, tripleS's Jiwoo, Woo!ah!'s Nana, Rocket Punch's Yeonhee and Juri, Cherry Bullet's Bora, and Weeekly's Jihan and Zoa held an upbeat wedding ceremony with "I Do". 

After the energetic performances by all three teams, the competition unveiled the current 'Top 7', the most likely candidates to make the final debut team EL7Z U+P. The 'Top 7' contestants on this day, announced in order were: Nana, Hwiseo, Kei, Yeoreum, Yuki, Yeeun, and Yeonhee. 

Unfortunately, these 7 contestants ended their 'Queendom Puzzle' journey at the semi-final stage: Fye, Riina, Miru, Soojin, Jiwon, Zoa, and Bora. This automatically moved the remaining 7 contestants - Dohwa, Elly, Suyoon, Wooyeon, Juri, Jiwoo, and Jihan - up to the final round, which will air next week on August 16 .
