Once you submit your preferred four-digit combination, you must bet a minimum of 1 MYR. You can place a larger bet to win a bigger prize. Then, you will have to choose between two additional opportunities, i-perm and roll.
Choosing i-perm allows you to bet on multiple permutations of your four-digit number. The number of permutations depends on how many repeated digits your 4D number has. For example, a variety of 2777 will give you four permutations (2777, 7277, 7727, 7772). This bet type costs you the same amount as a standard bet. However, the prizes you will be entitled to in the event of winning will be smaller.
On the other hand, a roll allows you to enter a 4D number in the form of R123 when placing a roll bet. Here, the R can be set in any digit in the number and stands for 0-9. Since you will bet on 10 unique 4D numbers, the minimum bet will be 10 MYR.
