Trenchlight: Sonar Survey

Choose a Star Credit play level. Matching symbols pay from the left across at least three adjacent reels on a 6 × 4 field. Wilds substitute for paying symbols. Collect Research Cores to unlock six Wild chapters separately at each play level. Sonar Sweep can transform the field. Outer-reel collectors gather visible coin values. Hold & Spin starts with three respins, resetting when a new coin lands. Collect the bonus pot, or choose a fair 50/50 Double; a loss removes the unresolved pot. Four successful Doubles collect automatically. Fictional credits only. Sonar Sweep reveals a four-position Wild cross around an inner-reel survey point.

Every result and credit change is resolved and saved on the server. If you lose connection, reopen this game to restore the latest round. An unresolved bonus must be completed before another round can start.

Sound is optional, and play reminders are available in Player Care. Social-casino outcomes do not predict real-money gambling success.
