The boss gauntlet

How a run is decided

After your sixth steal, the build plays up to ten games of one-on-one, one boss per rung, always in the same order. Every game is to 11. Win and you climb; lose once and the run is over, recorded as the round you fell in. Clear all ten and the card says so.

Which ten you face depends on your build target. Best Player runs climb the ladder from Boban Marjanović to Michael Jordan. A positional run faces that position’s own ladder. The cast changes but the difficulty never does: every ladder uses the same number for each rung, climbing 55, 60, 65, 70, 75, 80, 84, 87, 90, 93.

Your side of the matchup is the OVR printed on your card and nothing else. Offense, defense, synergies and positional weights all matter, but only through the OVR they produce; the simulation never looks at your six skills again. Boss difficulty is a matchup number on that same scale, not a rating of the real player. Nobody is claiming Dirk Nowitzki was an 80.

The math of one game

Every game starts from the gap: your OVR minus the boss’s difficulty, adjusted by your flaw if you are playing Budget. Three rules then decide it.

1. Big gaps skip the dice. If the gap, after any flaw penalty, is 12 or more, you win outright. If it is −12 or worse, you lose outright. Outside that window no upset is possible in either direction.
2. Inside the window, a curve sets the odds. An even gap is a coin flip, and near even each point of OVR is worth roughly eight percentage points. Before the roll, the game adds a seeded nudge to the gap, anywhere from −1.5 to +1.5. That nudge can tilt a close game by about a dozen points either way; it cannot rescue a lopsided one.
3. A clear edge is protected. If your OVR, before any flaw, is at least 3 above the boss, your chance never drops below 85%. The floor ignores flaws entirely, which matters a great deal once the weakness wheel is involved.

The rolls are seeded by the build itself: the six players you stole, your flaw, the mode and the target. The same build plays the same ten games, roll for roll, which is how a shared build code reproduces your result exactly. In Daily the attempt number is part of the seed too, so rebuilding your official six in a practice run can play out differently.

The scoreline is honest as well. The winner always has 11, and the loser’s total shrinks as the gap grows, with a point or two of noise. An 11–9 loss was a genuine coin flip; an 11–2 loss was decided in the draft. The scoring page has the one-paragraph version of all this.

What your OVR can expect

Put those rules together and the ladder sorts builds with uncomfortable precision. These odds come straight from the current simulation for a run with no flaw, as in Classic and Daily. The final two doors are rounds 9 and 10.

The first six rungs are a formality for a serious build. At 92 or better every one of them is an automatic win, and a mid-80s build usually gets through, although Dirk at six already takes a real bite. The gauntlet that decides runs is four games long: rounds 7 to 10, which on the Best Player ladder means Duncan, Kobe, LeBron and Jordan.

96 is the number that matters. It is the lowest OVR that sits 3 clear of Jordan, so the 85% floor covers every rung. Even then a perfect run is not guaranteed: the floor is a minimum you have to beat several games in a row. Builds from 90 to 95 are the ones the ladder was tuned to send to the final two doors; they usually get there. Against LeBron they range from a coin flip at 90 to a solid favorite at 93 and up; against Jordan, a 90 is a clear underdog and a 95 only a modest favorite. Below about 85, the run usually ends somewhere in rounds 6 to 8.

In Daily, the leaderboard sorts by OVR and then by bosses beaten. Two players on the same OVR are separated by these games, so the gauntlet is the tie-breaker even when it isn’t the headline.

Quick and crafty bosses

Some bosses carry one or both of two tags. In Classic and Daily they change nothing. In Budget they are what four flaws aim at: Matador Defense and Left Hand Decorative cost you power against quick bosses, while Tunnel Vision and Scouting Report Victim cost you power against crafty ones.

On the Best Player ladder the quick bosses are Iverson, Kobe and MJ; the crafty ones are Rodman, Duncan, LeBron and MJ. The tag on the last boss matters most, because the final door is the game a contender is most likely to lose. Jordan carries both, so a Best Player build has no safe matchup flaw. The positional ladders split differently, as the tables below show.

The Best Player ladder

The five positional ladders

A positional run swaps the cast, not the difficulty: round 10 is as hard on the center ladder as it is for Best Player. What changes is who you meet and which tags they carry, and in Budget that decides which flaws you can afford. The positional builds guide covers how each target weights your skills.
