Tomb Raider series: the 5x3 formula before and after the sequel
Unlike branded franchises that replace their engine with every return, Games Global's Tomb Raider series keeps a compact 5x3 action-slot formula and expands it through paylines and bonus structure. Tomb Raider established that approach in 2004 with 15 paylines, low-to-medium volatility, wild and scatter symbols, and free spins. Its restrained rules make Lara Croft's adventure theme the frame rather than a substitute for readable slot mechanics.

 Tomb Raider Secret of the SwordLatestGames Global | 2008 | 95.23% | Low volatility | 62 |
Tomb Raider Secret of the Sword widened the format in 2008 instead of overturning it. It doubled the line count to 30, shifted the profile to low volatility and added a multiplier, substitution effects and a separate bonus game. The sequel is consequently broader in feature structure but gentler in risk, preserving the original's five-reel identity while giving bonus events more ways to alter ordinary symbol outcomes.
