Betnero Lucky Rush

If you fancy being among the 5,000+ weekly winners and competing for up to £200K in cash rewards, Betnero’s promotion this weekend might be for you.

Known as Lucky Rush, this is a Playtech-specific competition, where you must play their titles and look to climb up as high as possible on their leaderboards. With each spin made, you can climb higher up the rankings in the leaderboard that you have been placed in.

A total of 45 leaderboards, each with between 5,000 and 10,000 players, exist, with prize pots of £100,000 and £200,000 available. These are network leaderboards, meaning you will play against other players at other participating casinos with Playtech games.

The promotion runs from 06 March 2026 to 17 January 2027, giving you plenty of time to play. There are no wagering requirements or a minimum bet to participate, but it is exclusively for
Playtech games. The eligible games include:
4 Crazy Cluckers
Big Bad Wolf: Cash Collect & Link
Buffalo Blitz Cash Collect.

LuckyMate Drops & Wins

A Pragmatic Play staple, the Drops & Wins tournament is available to play in at LuckyMate this weekend. There is a whopping £25 million in cash prizes, with more than 5 million chances to win, thanks to 96,900 weekly prizes.

You just need to play selected games, collect 3 Wheel Pieces and unlock a guaranteed reward: Bonus Spins, instant cash, or multipliers up to 100,000x.

The competition runs between 4th March 2026 until 3rd March 2027. You will need to opt in to the tournament each week you want to participate, with all wagers on Pragmatic Play slots eligible.

As always, read the T&Cs fully before playing to understand the promotion.
