The **APPARATUS 2** slot runs on a **5×4 setup** with up to **50 adjustable paylines**, giving players full control over the volatility and bet size. The game’s **Wild Symbol** substitutes for all regular symbols, while the Scatter unlocks the bonus feature. Landing **10, 11 or 12 Scatters** awards **7, 15 or 30 Free Spins**. During the bonus round, winning symbols become sticky and trigger **Respins**, giving additional chances to enhance or extend the current win. The Respin loop ends only when no new or expanding combination appears, after which the feature continues with the next Free Spin. The bonus is played with the same bet that triggered it.
