}READ THE TICKET, NOT JUST THE BALLS
Five picks.
Three matches.
Galabet uses reproducible shuffles for both this draw and Mines. Here, ten numbers become a public set to compare with your ticket. In Mines, the shuffled positions must stay concealed while the board is active. The shared foundation is the shuffle; what the player can see depends on the game.
Without replacement.
The mapper shuffles the numbers 1–40 and takes ten. A number cannot appear twice in that set. Reproducing the shuffle uses 39 fractions.
Sorted for comparison.
The result is returned in ascending order. The ball display shows that sorted set; it does not claim to preserve a physical extraction order.
Hits before payouts.
The ticket explains exactly which picks matched. A payout needs a separate table indexed by pick count and hits; this demonstration reports matches without settling chips.
SAME DRAW SIZE, DIFFERENT TICKETS
Three hits.
Out of how many picks?
A hit count needs the ticket size beside it. Three matches on a three-pick ticket and three on a ten-pick ticket have different probabilities and use different payout rows. Read both parts together.
Picks, drawn numbers and matches answer different questions.
The submitted picks describe the ticket. The drawn set comes from the mapper. Their intersection supplies the hit count. Preserve all three, with the chosen table version, so a later support check does not depend on the player's current selection.
A multiplier below 1× can still return chips.
A 0.25× result on a 100-chip stake returns 25 chips: the net change is −75. Whole-chip rounding also matters on a small stake. A receipt should say what was returned and what changed in the balance.

The comparison explains the hits. Payouts come from the selected demo table and must be shown separately.
