๐ LEARN ยท LINEUP BUILDING
๐ How to Build & Enter the Best Lineups โ Click-by-Click
The contest decides what a good lineup is. This guide shows you exactly which buttons to press so every entry you upload is built for the contest you're actually playing โ 1 lineup or 150.
โก The 30-second version: pick your real contest from the dropdown โ lock your beliefs (or set your rules) โ Build โ Sim โ sort by the stat that wins YOUR format โ Export to DK. Every step below is just that, slower.
๐๏ธ THE HAND-BUILDER โ click by click (you pick, we perfect)
1
Open it: Menu โ your sport โ
โญ Hand-Builder (
MLB ยท
MMA ยท
PGA). Tonight's slate loads automatically โ MLB has a slate dropdown top-left if more than one is live.
2
Lock your guys: in the player table, tap the first column next to a player. One tap = ๐ locked into every lineup. Two taps = ๐ซ banned. Third tap clears it. (MLB: tap a roster slot on the left, then tap the player you want in it โ โ removes him.)
3
Pick your mode: ๐ต Cash (pays for floor, no risky stacking) or ๐ GPP (pays for ceiling, builds correlation). This changes the engine, not the label.
4
Set your rules (MLB): type teams into ๐ซ exclude teams to ban them from auto-fills ยท pick a stack shape (Auto follows your mode; or force Max 5 / 4 / 3 / No stacks) ยท toggle ๐ Late Swap when games have started so fills only touch players DK still lets you change.
5
Set the count and hit Build: every empty seat fills smart โ cap-legal, salary-maxed, diversified so 20 lineups aren't 20 copies, real captains only where the format has captains.
6
Export DK CSV: ready-to-upload files with player IDs, auto-split at DK's 500-per-file limit. Upload in the DK lobby โ Upload Entries.
How many to build: single entry โ build 20, submit the best Win% one. 20-max โ build 60, keep 20 different stories. 150-max โ lock ONE anchor max and let diversity work.
โก THE AUTOMATIC WAY โ click by click (you set rules, we drive)
2
Pick your REAL contest from the dropdown. This is the whole secret โ every contest is loaded with its true field size, fee, and payout curve. The sim runs YOUR tournament, not a generic one.
3
Playing something not listed? Use Custom: type the field size, entry fee, and pick the payout shape (top-heavy GPP / small-field / single-entry / flat cash). The Monte Carlo runs those exact numbers.
4
Set your rules: exposure caps (nobody over X% of your set), min salary, max dupes, and any core you want built around. Nothing is forced โ your caps hold.
5
Hit Build โ Sim. Thousands of lineups get built, then simulated inside your contest against a field that plays like the real one โ correct chalk, correct captain ownership. Locked players ride in every lineup and rank first.
6
Sort, slice, export โ next section.
โ๏ธ SORTING THE POOL โ enter only the killers
| Your contest | Sort by | Why |
| 150-max / multi-entry GPP | True ROI โ then RAROI | Top slice of a 5,000 pool by ROI is already elite; the RAROI re-sort keeps the ones that profit without a miracle. |
| Big-field tournament (one shot at glory) | Win% / Top-1% | Tournament winners usually sim NEGATIVE average ROI โ our tracked winner simmed โ29.8% and returned 5,455%. Ceiling wins trophies. |
| Single entry | Win% | One bullet can't average its way to first. Commit to one script. |
| Cash / double-up | Cash rate | Boring is correct. Highest floor survives the cash line. |
Final gate before export โ the ฮฃown badge: real big-field winners land in an ownership band, and the badge turns green when your lineup is inside it. Too chalky = you split the pot when you win. Too thin = you need three miracles. In the band = leverage without lottery.
๐ LATE SWAP โ fixing lineups after early games start
DK's rule: once a player's game starts, he's locked in that seat โ everyone else can still be moved. Our tools: in the MLB Hand-Builder, flip on ๐ Late Swap โ fills will only use players from games that haven't started, so a re-fill never suggests an illegal move. In MMA, the builder's Late Swap panel lets you mark finished fights and re-optimizes every still-open seat from the loaded pool. Your builds save automatically, so come back mid-slate and your lineups are waiting.
The one-line philosophy: lock your beliefs or set your rules โ sim against YOUR contest โ sort by what wins THAT format โ export. We ask the contest 10,000 times what a good lineup looks like before you spend a dollar. Every pick we publish gets graded, win or lose.
