Uncrossable Rush calculators
For Uncrossable Rush a target multiplier is the lane payout you would bank by cashing out, so the first calculator shows the chance that one crossing, under this site's fixed mix of modes and stopping lanes, pays at least that much. The second applies the 4% house edge to your stake and number of rounds, and the third estimates how likely a run of collisions is and what a doubling system would lose across it. The game pays 10,000x at most, so higher targets are out of reach.
