Cluster Merge & Level Up is an innovative payout mechanic that dynamically transforms winning symbols.
Upon forming a cluster win, the symbols involved merge and upgrade to a higher-value version of themselves.
This process continues through a fixed progression, typically across 9 distinct levels of symbol value.
Remaining winning symbols (if any beyond those merged) then disappear, triggering a cascade for new symbols.
The feature offers continuous progression and increasing payout potential within a single spin sequence.
