123 Boom!

A Pirate Slot With a Twist You Flip

123 Boom!, from 4ThePlayer, sets its action on the high seas with two ships doing battle around the edges of the reels, but the real hook is the Slot Slider mechanic — flipping your phone, or hitting the Spin Mode button on desktop, rotates the entire grid between two distinct play styles.

Slide Spin vs Top Spin

In Slide Spin mode, reels spin right to left and pay left to right, the more conventional of the two setups. Switch to Top Spin and the reels instead spin top to bottom, paying bottom to top — a genuinely disorientating change at first that takes a few spins to adjust to, but adds a layer of novelty rarely seen in this genre.

Grid and Paylines

The game runs on a 5-reel, 4-row configuration with 1,024 ways to win, evaluated in whichever direction the current mode dictates. Winning combinations need three or more matching symbols landing on adjacent reels; rows don't factor into the count, only the ways-to-win structure.

Transparent Stats

4ThePlayer has a reputation for laying its numbers out in full, and 123 Boom! is no exception. The RTP sits at 96.4%, volatility is rated medium-high, and the documented hit rate comes in at one winning spin in every 3.5 — a genuinely useful figure that tells you fairly precise fairly frequent returns are part of the design, even if their size will vary. A separate bonus frequency of roughly 1 in 203 spins gives an idea of how often the feature round itself should appear.

Betting Range

Stakes run from £0.10 to £50 per spin, playable on any device, with the Slot Slider available regardless of whether you're spinning on mobile or desktop.

Max Win

The ceiling here is 14,727x the stake — not the biggest number in the genre, but a solid, achievable target given the medium-high volatility and a hit rate that keeps the reels ticking over at a reasonable pace.
