Function take in array of string return only strings with that have number(s) in them. Or return empty array if none

The function has 1 parameter: an array. It should iterate through the array and return strings that contain a number in them. If none of them have an number it will return an empty array.

The code I have written so far seems too verbose. Sometimes it does not return the correct value. I am looking for any ways to shorten the code or improve it.

function numInStr(arr) {
    var stringsWithNum = [];
  for(var x = 0; x < arr.length - 1; x++) {
    for (var y = 0; y < arr[x].length - 1;y++) {
      //console.log(typeof arr[x][y]);
            if('0123456789'.indexOf(arr[x][y]) !== -1) {        
                stringsWithNum.push(arr[x]);
        break;              
      }
    }
  }
  return stringsWithNum;
}
