How to use: Configure the lottery game (e.g. Vietlott Power 6/55), ticket price, jackpot size, and how many tickets you hypothetically buy over time. This tool computes exact odds and expected value to show how unlikely jackpots are and why lottery is mathematically negative-EV. It does not encourage real-world gambling.

Different models have different capabilities and costs.

Total numbers to choose from. For Vietlott Power 6/55, n = 55.

How many numbers you pick on each ticket.

Face value of a single ticket in Vietnamese Dong.

Estimated jackpot size. Use a rough average if it varies over time.

How many lottery drawings you hypothetically participate in (e.g. 104 draws ≈ 2 years at 2 draws/week).

How many tickets you buy each time there is a draw.
