The top 10 Both Ways slots ranked by RTP — expert reviews, free demos, and full specs.



How Both Ways Works
Both Ways — sometimes listed as "243 Both Ways" or simply "pays both ways" — is a payline modifier that evaluates winning combinations in two directions simultaneously: the standard left-to-right read starting from reel one, and a mirror right-to-left read starting from the final reel. Any matching combination that qualifies in either direction generates a payout, and combinations that qualify in both directions pay twice.
NetEnt made the mechanic mainstream with Starburst (2012) and Twin Spin (2013), two games that remain among the most widely distributed slots in the industry over a decade later. The mechanic's appeal lies partly in its transparency — players immediately understand that more directions means more chances — and partly in the fact that it requires no additional complexity or special features to explain.

The perceived effect of paying both ways is a meaningful increase in win frequency — not because the base RTP changes (it typically does not), but because combinations that previously missed by starting on the wrong side of the reel now qualify. A three-of-a-kind combination landing on reels 3, 4, and 5 would fail on a left-to-right-only layout. On a both-ways layout it pays from the right. This recovers wins that players would otherwise experience as losses, smoothing the session variance.
Starburst builds on this with an additional expanding wild that locks and triggers a respin. When a Starburst wild lands, it expands to cover the entire reel, re-evaluates wins in both directions, and awards a respin. Landing additional Starburst wilds during that respin extends the sequence. The combination of both-ways evaluation and expanding-wild respins has made Starburst the default "low-risk" recommendation at the vast majority of online casinos — its simplicity and consistent return profile make it uniquely accessible.
Thunderkick's Esqueleto Explosivo takes the format in a different direction, adding a Mucho Multiplier that increases with each cascading win and applies to both-ways combinations — demonstrating that both-ways is a foundation mechanic compatible with complexity layers rather than a purely simple format.
