slot machines
Wild Portals is a futuristic slot machine from Big Time Gaming (BTG). The concept is simple on paper, but very "BTG" in execution: Megaways™ (up to 117,649 ways) and a special symbol, the Wild Portal, which can increase multipliers over time. 🎰

The core of the game: Wild Portals that "clear" a symbol
On every spin, a Wild Portal (a 2×2 block) can appear on reels 2 to 5. When it activates, it reveals a symbol: all of its occurrences are removed from the reels, causing falls/cascades and increasing a multiplier attached to the Wild. If a winning combination is formed, the payout is applied with the current multiplier.
Free Spins: a guaranteed Wild Portal on every spin
The Free Spins mode is the perfect playground for this mechanic: BTG announces that a Wild Portal is guaranteed on every free spin. The multiplier can continue to increase throughout the bonus, and it is carried over from the triggering spin to the free spins (which can start the bonus with some momentum already).
In the event of a retrigger, 3 scatters retrigger the bonus and add 2 free spins, plus 3 per scatter beyond the third.
Win Exchange™: exchange a big win for a bonus chance
A BTG specificity: Win Exchange™. When you hit a "big" win (according to the game's thresholds), you can choose to exchange it for a chance to trigger the Free Spins. In Wild Portals, BTG describes in particular:
From 75×: option to exchange 75× the bet to get 8 Free Spins.
Between 25× and 75×: option to exchange the entire win to try to get 8 Free Spins.
Note: if the Free Spins start via Win Exchange, the Wild Portal multiplier starts at 1. And the Win Exchange is not offered if the Free Spins have already been triggered.
Quick tips for a "clean" session
Do not overpay for the "swap": Win Exchange is tempting, but it is an arbitrage. Keeping a sufficient bankroll remains a priority.
Accept the variance: the game clearly aims for the "big multiplier". Quiet streaks are part of the package.
Compare Megaways: if you like the style, also test Wings of Ra MegaWays (different atmosphere, same idea of a very large number of ways to win).
Why Wild Portals appeals so much to BTG fans
Because it condenses what BTG knows how to do: a clean sci-fi theme, clear mechanics (Wild + multiplier), and a very high ceiling (29,580×). If the goal is to "hunt" for big hits on a Megaways, it is clearly a serious candidate.
