Part 4

Round multipliers and snipe thresholds — using the Snipe Calculator

Use the round multipliers (2×, 1.6×, 1.3×, 1.1×) to find the bid that blocks a snipe and the one that lands it. Example: White Dragon King, 300,000.

Two cases

To block a snipe, multiply (× multiplier + 1); to land one, divide (÷ multiplier + 1).

To avoid a snipe: you expect a rival to bid X. How much must you bid to end it this round? → X × multiplier + 1.
To snipe: you want to take it for X. How low does a rival have to bid? → X ÷ multiplier + 1 is your bid.
Multipliers: 2× in round 1 · 1.6× in round 2 · 1.3× in round 3 · 1.1× in round 4. No multiplier in round 5.

Here are the blocking and sniping bids for White Dragon King (300,000), round by round.

Round	Multiplier	To avoid a snipe (× multiplier + 1)	To snipe (÷ multiplier + 1)
1	2×	600,001	150,001
2	1.6×	480,001	187,501
3	1.3×	390,001	230,770
4	1.1×	330,001	272,728

If the result has decimals, round down, then add 1. The site converts multipliers like 1.1 into whole numbers in thousandths to avoid floating-point errors (111,111 ÷ 1.1 = 101,009.999…).

Round 1 is hard to overturn (2×), while in round 4 beating the top bid by just 10% wins.

With a 2× multiplier in round 1, even a slightly higher rival bid is hard to overturn. A round-1 all-in (ending it in one go) has to beat twice the rival's expected bid.
Round 4 is 1.1×, so beating the top rival bid by just 10% wins. Round 5 has no multiplier, so the last round is a straight fight for the highest bid.
The Snipe Calculator's [Fill from items] lets you add several collectibles and puts their total into the price field — the same way the Combo Finder works.
