Bermuda
Hit the target for each round or risk losing your score.
How to play: Each round has a specific target segment — one of the numbered wedges or the bullseye at the center of the board. Hit the target and score its value; miss the segment entirely and your current score is split in half instead. Play carefully through all the rounds — the player with the highest total at the end wins, as long as they haven't lost too much along the way.
Other darts apps call this same core mechanic — miss and your score gets halved — "Half It" or "Split Score." Those variants start their target sequence at number 15 instead of 12 and skip a final round requiring a double bull; Autodarts only implements Bermuda, not those variants.

Bermuda has no configurable settings beyond selecting the mode itself.

Personal data redactedNamed after the infamous ocean region where ships and aircraft mysteriously vanish, this game mode challenges players to hit a sequence of specific target zones. If a player fails to land at least one dart on the designated target during their turn, half of their accumulated score instantly disappears. This unforgiving penalty mirrors the legend itself, causing a commanding lead to vanish into thin air after just three bad turns.
