If the number is too large, he advances his pawn to the bottom square of the stairs, then moves it back by the number of squares corresponding to the difference between the number to be made and the number made; taking the example again: if the player rolls 4 with the dice, he will move the pawn forward three spaces, then move it back one space.
If the number is too great, he advances his pawn to the lowest rung of the staircase, then moves it back by the number of rungs equivalent to the difference between the desired outcome and the actual roll; taking the same example: if the player rolls a 4 with the dice, they will advance the pawn three steps forward before moving it one step backward.
