How F777 Fighter Works

F777 Fighter is a crash-format multiplier game developed by Onlyplay and released in December 2020. Each round begins with a military fighter jet taking off from an aircraft carrier. A multiplier starts at 1.00x and climbs continuously. The round ends when the jet is shot down — the crash — at a point determined before the round begins by a cryptographic algorithm. Players must press the "Take" button to cash out before that crash occurs. If the jet crashes before a player cashes out, the entire stake for that round is lost.

The crash point is predetermined each round. It is not influenced by the number of active players, bet sizes, or when any individual clicks cash out. Each round is statistically independent of all previous rounds.

Betting and Cashout Mechanics

F777 Fighter provides two separate betting panels per round, allowing players to place two independent bets simultaneously with different amounts and different cashout targets. Bets start at $0.10 and go up to $50 per panel. Players can place bets manually during the brief betting window between rounds.

  • Manual Cashout: The player presses "Take" at any point during the flight to lock in the current multiplier. The payout equals the stake multiplied by the multiplier at the moment of cashout.
  • Auto Cashout (Auto Take): Players set a predetermined multiplier target before the round starts. The game automatically cashes out the bet when that target is reached, removing the need for manual action. Note: using Auto Take at low multipliers reduces effective RTP, as it removes eligibility for the progressive jackpot, which only triggers on rounds reaching 3.00x or above.
  • Dual Bet Strategy: The two betting panels can be used with different cashout settings — for example, one panel set to auto-cashout at a conservative target and the other managed manually for higher multiplier attempts.

Multiplier Growth and Range

The multiplier begins at 1.00x at the start of each round and increases in real time as the jet flies. There is no published maximum multiplier cap — theoretically, the multiplier can grow without limit. The game can also crash at 1.00x, resulting in no win. High volatility means that large multipliers occur less frequently, and most rounds resolve at lower values.

Special Features

Aerial Refueling Bonus

During a round, a refueling aircraft may randomly appear and connect to the fighter jet. When this occurs, the current multiplier receives an instant percentage boost of 20%, 40%, or 60%. For example, if the multiplier stands at 5.00x when a 40% refuel triggers, the effective multiplier jumps to 7.00x. Multiple refueling events can occur within a single round. Players who have already cashed out before the refuel event do not benefit from the boost.

Progressive Jackpot

F777 Fighter includes a network-wide progressive jackpot displayed above the playing field. It can trigger randomly on any round where the multiplier exceeds 3.00x. When triggered, all players who remain active in that round — meaning they have not yet cashed out — receive a share of the jackpot pool. Each player's share is proportional to their bet size relative to the total bets of all qualifying players in that round. The jackpot is funded from the game's house edge and is already included within the 95% RTP figure.

Provably Fair Verification

F777 Fighter uses Provably Fair technology. The outcome of each round is determined by a cryptographic hash generated before the round starts. Players can verify the fairness of any completed round by checking the published hash against the round result using standard SHA-256 verification. This means neither the casino nor the provider can alter a round's outcome after it has been committed.
