Round 1: Math and RTP at the round level
Both games run 97% base RTP and a 3% house edge, so the shape of the distribution is identical. Where they part ways is the ceiling: Aviator caps multiplier at 10,000x with a flat $10,000 payout cap, Lucky Jet caps at 10,000x but trims payout at $500,000, redistributing tail probability back into the 100x-10,000x band.
Aviator's math is the category reference. Probability of reaching multiplier m is roughly 0.97/m, so 2x hits on 48.5% of rounds, 5x on 19.4%, 10x on 9.7%, 100x on 0.97%. About 3% of rounds crash instantly at 1.00x, which is the house edge showing up inside the distribution. The payout cap is $10,000 per round regardless of stake: at $100 per panel, you need 100x just to touch the cap. Operators can ship 94-96% variants, so the RTP you actually play is whatever is exposed in the in-game info panel, not the provider default.
Lucky Jet follows the same 0.97/m shape with one structural twist. The theoretical ceiling is 10,000x, but the operator caps per-round payout at $500,000. At $50 stake the 10,000x cap still works at full range and a peak round pays $500,000. Above $50 stake the effective multiplier ceiling compresses: at $500 per panel the cap kicks in at 1,000x, at $1,000 it binds at 500x. That sounds punitive, but it flows from a $1,000 per-panel cap no other 97% crash matches. For a $1-$10 recreational session the cap never fires across thousands of rounds.
