C's 14 is not greater than the combined value of A&B's 7s; therefore A and B leave their cards in front of themselves.
After C's play, A begins their turn by discarding their 7 (without drawing a replacement). Since B's 7 also "joined forces" with them, B discards their 7 as well (on A's turn, also without drawing a replacement). A then plays a card.
Ties never result in a flush (discard & draw). Continuing the example:
A plays a 10 (C's 14 stays)
B plays a 5 (A's 10 and C's 14 stay)
C discards their 14 (without drawing) and plays a 5 (combining with B's 5 for a value of 10. A's 10 and B's 5 remain)
A discards their 10 (without drawing) and plays an 11 (beating B&C's value of 10). B and C discard their 5s and draw replacements
Hope that helps!
Yes got it now. Thanks!
