Bhabi

The card game you already play with your friends and family, now on the phones that are already on the table. Make a room, read the four letters out loud, and whoever is around joins. Three to six of you. No sign-up, no password, nothing to fill in — you will be dealt in before anyone has finished asking what the code was again. The whole deck goes out, so hands are uneven. Aces are high and there are no trumps. Follow the suit that was led if you can, and if everybody manages it the highest card takes the trick and those cards are gone. The trouble starts when somebody cannot follow. The trick stops dead, and whoever put down the highest card of the led suit picks up the lot. You watch your hand come down to four cards, then three, and then somebody plays a heart on a run of spades and you are holding nine again. Get to zero and you are out, safely. The last one still holding cards is the bhabi, and everybody will make sure they know it. Free, no advertising, nothing to buy. You will need an internet connection and two friends.
