    How to play UK Lotto: numbers, two rounds and the Bonus Ball

    Play a local UK Lotto simulation with six numbers from 1–59 and the two-round format introduced in June 2026. This guide explains your line, both draws, the Bonus Balls and the controls on this page.

    One standard line
    6 different numbers · 1–59
    Each draw
    Two separate rounds
    Bonus Ball
    Drawn separately in each round

    1. How a UK Lotto line works

    1. Choose six different numbers between 1 and 59. You do not choose a seventh number for the Bonus Ball.
    2. Select the draw and register your entry through The National Lottery. Keep the ticket or online confirmation; generating numbers here does not enter you.
    3. Check the same line against Round 1 and Round 2 separately. Each round has six main numbers and a Bonus Ball. Your line can win in either round or both.
    4. Count matches within one round. Two or more main-number matches can win a prize. Five main numbers plus that round’s Bonus Ball form a separate prize category; six main numbers qualify for the jackpot category.

    2. What the June 2026 change means

    One Lotto line now participates in both rounds automatically. The jackpot is shared across the rounds, while the other prize categories are paid per round. Use the current operator’s prize table rather than an older guide describing a single round or a free Lucky Dip for matching two numbers.

    3. Play the UK Lotto simulator on this page

    More options — Your line, combinations and chances. Experiment with numbers — Run a series and compare matches.

    Press Lucky Dip for six different numbers from the full 1–59 range. Enter one number in each box. Your line stays for the next draw.

    Press Start the machine. The same line is checked against two independently generated rounds, each with six main numbers and a Bonus Ball drawn from the remaining numbers. The Bonus Ball cannot repeat a main number within its round.

    A ✓ marks a main-number match. Each round shows its own match count and whether your line contains its Bonus Ball. A Bonus Ball match is separate from main-number matches; it does not turn five main matches into six. It is relevant to the five-plus-Bonus prize category.

    Keep your line and simulate again, or create a new line. History keeps the last 20 simulations with both rounds and your original line; copy or clear it using the buttons. Reloading clears history.

    This is a free simulation of the basic UK Lotto game. It does not sell tickets, calculate prize amounts, reproduce jackpot roll-down payments or include Lotto HotPicks. Results are invented locally.

    4. Before checking a ticket

    Match the draw date, round and game name on your actual ticket. A sorted display is just a way to read numbers; their order does not affect main-number matching. Use the official ticket checker to establish any prize.

    This site does not sell entries, predict winning numbers or improve the odds of an individual line. A past result does not make a number due to appear.

    Bulk draws

    Number of repetitions: 1000 → Run batch.

    1–1,000,000 simulated draws. You can stop a series at any time.

    A draw with a win is counted once, even if several rounds win. A win means a prize-qualifying outcome, including a refund; it does not mean profit. No prize amounts are calculated. Tables cover completed repetitions only.

    Frequently asked questions

    How are the simulation results generated?

    The browser draws numbers at random according to the selected game's ranges and rules. Within a single main-number draw, numbers do not repeat; a later draw may contain the same values.

    Does generating a line enter me in a lottery?

    No. This page is a no-money simulator. It neither registers a ticket nor predicts official results. A generated valid combination has no advantage over another valid combination.

    What games are supported?

    This version simulates UK Lotto: six numbers from 1–59, two rounds and a separate Bonus Ball in each round. It supports your own line or Lucky Dip, match checking and session history.
