Dead, Dead or Deader has a configurable RTP, so check the value running at the casino in the game's info panel. That panel is the reference for the other games too, because studios often offer several configurations.

Volatility and bonuses: how to choose

When playing with a bonus, the choice of game matters as much as the bonus itself. Nolimit City's extreme-volatility titles – Mental, Mental 2, Fire in the Hole 3, Duck Hunters: Happy Hour and Dead, Dead or Deader – pay rarely but big, so reaching the end of wagering is uncertain. Merge Up's high RTP lowers the expected cost of wagering if the terms count it. Wild Bandito's medium volatility gives a steadier ride. Chicken Train is a crash-style game that terms often treat separately.

What to check before every game

Three things. First, the RTP in the info panel. Second, in the bonus terms, that the game is not excluded and what it contributes. Third, the stake: with a bonus, set it below the cap before the first spin. The full list is on the bonus terms page.

Categories in the lobby

Beyond the eight titles covered here, a casino lobby usually splits into categories: slots, live casino, table games and fast crash-style games. Categories also differ for bonuses, because their contribution to wagering can vary. These are covered on the slots, live casino and table games pages.

Frequently asked questions

Which of these games is best for clearing a bonus?

Medium-volatility Wild Bandito usually gives the steadiest ride. Whether a game counts towards wagering is always decided by the bonus terms' contribution table.

Where can I see a game's exact RTP?

In the game's info panel or help screen, once launched at the casino. Studios may offer several configurations, so that value is the reference.

Can I try the games for free?

Many casinos offer a demo mode, but availability can differ by account and country. Demo play does not count towards wagering.
