In a traditional Russian wedding, before taking the bride away to get married, the groom has to pay “ransom” to her friends, cousins, neighbors who stand in his way at the door of the parents’ house and the bride’s room. The “ransom” can be paid in money, treats or tricks - sing a song, tell a joke, solve a riddle, etc.
During the wedding reception it is customary for guests to complain that their drink is very bitter, and everyone starts yelling “Bitter! Bitter!”. This is the signal for the newlyweds to get up and kiss “to sweeten the drink”, and the guests mark the duration of the kiss by counting up the seconds.
I have a friend who is Bulgarian and she said there is a tradition whereby the bride and groom rip apart a piece of bread and whoever gets the larger piece “wears the pants” in the family. Kind of akin to how we break apart a turkey wishbone.
Chinese weddings have this too. They are called wedding door games when the groom or sometimes his groomsmen have to overcome “challenges” to show the groom’s love for his bride and deserves to be her husband.

In east indian weddings after the ceremony is over and the bride goes to the grooms home fun games are played.
A tray of water is mixed with milk and sindoor (vermillion) and it is filled with coins and a ring. Whoever finds the ring four out of seven times will rule the household.
In another game where the bridesmaids of the bride, particularly the bride’s sisters and friends who attend the wedding, attempt to stealthily take away and hide the shoes of the bridegroom before he enters the wedding mandap(tent where the ceremony takes place)
The men from the groom’s side, in turn partake in concealing and protecting the shoes of the groom, thus not allowing the women to succeed in getting an opportunity to take away the shoes. If the girls succeed, which is more often than not, then they lovingly demand a reasonable sum of money from their brother-in-law, in exchange for his shoes, after the ritual is done and the groom is to leave the ‘mandap’ with the bride. The groom is left with no choice but to pay the ransom amount to his demanding sisters-in-laws to get his shoes back.
Another game is the Henna Name Search.
Usually the bride gets mehendi(henna) on her palm before the wedding ceremony in which the initial of groom’s name is written in intricate pattern. The groom has to find out that letter from his wife’s hand.
