Devil Fire

Named "Free Game" on the spec table. In the free games each Little Devil that lands can expand into more Little Devils, and the studio says that expansion also multiplies the payout; nine Little Devils there is the route it names to the 10000x ceiling. It publishes no trigger rule beyond "between the 2nd and 4th rounds", no expansion odds and no multiplier values.

Where most of the return lives in modern slots. How long it takes to reach is the feature frequency.

The spec table gives 20 lines. The studio's page draws no line map, so which cells each line crosses is in the game's own info screen rather than on its site.

The baseline every other evaluation system varies from. A low line count concentrates the return into fewer, larger wins.

Named "JACKPOT" on the spec table. Three or more Little Devil symbols trigger the jackpot bonus, and the studio's description says up to nine can land in the base game for a 2000x payout. It publishes no prize for a count below nine and no odds of landing any count.

Nothing changes in the maths beyond what the paytable already says. The label is marketing, and a prize called a jackpot is not evidence that the game pays more often or more.
