21 is a game of numbers. You will guess numbers from 1 - 20 then ESP the number to the Host. The Host will then announce a number. The sum of your number and the Host's number should be 21 or below to get points and if you get a total of 22 or more you will get zero points. Every sum of your numbers and Host's number will be counted as your points. At the end of the last round the Host will announce the grand total of points of each player. There are only 3 winners in every game which are the top 3 highest points. The prizes are vouchers which you can use to buy in "The Prize Market" at Temple Street Locale. You can also win Door prizes which are vouchers too.
