switch(user) {
case 'chess':
console.log("Its played well by mind");
var 1st=prompt("Are you playing this game 1st time? ");
var champ=prompt("Are you champion of this game?");
if (champ==='yes'){
console.log("all the best");
}
else{
console.log("ohhh, lets take 1st experiance");
}
break;
case 'cards':
console.log("its played bye trics also");
var 1st=prompt("Are you playing this game 1st time? ");
var champ=prompt("Are you champion of this game?");
if (champ==='yes'){
console.log("all the best");

i would be very careful with numbers in variable names, in particular at the first position:

var 1st=prompt("Are you playing this game 1st time? ");

i would just called the variable first
