A SCRATCH-OFF super fan is sharing some of his tips on how to win big.

Uncle Billy John Jr uses his TikTok to share his wins, aiming to help others improve their chances of hitting the jackpot.

His bedroom walls are covered from floor to ceiling with scratch-off cards he's taken chances on.

Through hundreds of cards of trial and error, he's developed his own strategies to get more wins than losses.

In one of his TikToks, he "cracked the lottery secret" and shared his tips to help others get their hands on some cold hard cash.

There are so many theories and strategies out there, but it's important to remember the lottery has never confirmed nor denied any of the claims.

His top seven strategies

Uncle Billy first suggested buying several of the same tickets at once rather than a bunch of different ones.

Although crossword cards can be time-consuming, he said they often have better prizes.

He also noted players should avoid special holiday cards unless they're picking them up in the middle of the month.

It is said that there's a better chance of winning with the cards in the middle of the stack than at the beginning or end.

He said his best winnings come from multiplier scratchers, which let you multiply your prize over and over again.

Tickets that offer one thing or another, known as this or that scratchers, have terrible odds and barely get him any wins.

Uncle Billy said pricier $30 tickets offer the best odds to win.

While he didn't offer a reason as to why he said to avoid any cards that have the number seven as part of the game's title.

Scratch-off tickets can offer huge winnings that rival those of other lottery games.

An anonymous man picked up three winning lottery tickets in one day in New Jersey.

He started off his day by buying a scratch-off ticket that won him $50.

He was so pleased with the $50 win that he decided to test his luck again and bought a second scratch-off ticket the same day.

To his amazement, he won again, doubling his earlier prize - with a $100 win.

The anonymous player went about his day before deciding to test his luck one more time.

He picked out a ticket: the $3,000,000 Ultimate Riches scratch-off game.

When he scanned the ticket a message popped up asking him to see the clerk.

The clerk let him know he had won a huge prize, so he scratched the ticket and was thrilled to see what he thought was a $300,000 prize.

A moment later, he discovered that the actual prize was 10 times the amount on the ticket - meaning he had just won $3million.

In just a matter of hours on one serendipitous spring day, the player won a total of $3,000,150 for all three of his tickets.
