What the mechanic does
What a Development tool means?
An internal development or demo tool for the game. It does not affect a player's outcome at the casino.
Why these games?
A mechanic is listed only if it is marked in the game's own feature list. We do not infer mechanics from videos or ads.
Does this mechanic raise the RTP?
Not automatically. RTP is a game-specific figure and is stated separately on each game's page. The mechanics tell how wins are formed — not how often they occur.
