The short version
- Tap Spin. The reel lands on a real player. Tap a glowing body part to put that player's rating into that attribute slot.
- Fill every slot. Your OVR is a weighted average of the slots, and the important slots weigh more.
- You get three one-shot power-ups per build in most games: Re-spin (spin again), Snag (take the neighbor card instead) and Boost (upgrade to the player's Prime card).
- Then Simulate Career. The sim is seeded from your build: same build, same career, every time. Awards, rings and the Hall of Fame verdict all come from your slots.
- Post to the leaderboard. Daily boards reset at midnight UTC; all-time boards rank by OVR.

Step 1: Spin the reel
Press Spin (on desktop, the Space bar also spins). The reel is a weighted random draw from that sport's player pool: current players with real ratings, plus retired legends. It stops on one player and shows their card with the ratings that matter for the open slots.
You cannot pick who lands. What you control is where each landed player goes, and when to spend a power-up to change the outcome.
Step 2: Assign the player to a slot
Each attribute slot maps to a body part on the figure (in baseball, for example, Velocity is the bicep and Stamina is the legs). Eligible parts glow and preview the rating you would get. Tap one, the headshot flies in, the region takes the player's team colors, and the OVR gauge counts up.
The rule that decides everything: a player only gives you the rating they have in that one attribute. A 99-overall superstar with an 80 in the slot you put him in is an 80. A role player with an elite single skill is often the better pick for that slot. GoatLab is a game about specialists, not stars.
Step 3: Use your three power-ups well
| Power-up | What it does | When to use it |
|---|---|---|
| Re-spin | Discard the landed player and spin again. | When nothing on the card fits an open slot above your current average. Never burn it early on a merely "fine" card. |
| Snag | Take the card to the left or right of the landed one instead. | When you can see a better neighbor. Read the reel before you decide; the neighbors are visible. |
| Boost | Upgrade the landed player to their Prime card (their peak-season special edition). Ratings only go up, never down, and Primes can push past 99. | On a player whose Prime is dramatically better in the slot you need, ideally a slot the OVR formula weighs heavily. |
Most games give you one of each per build. Some quests reward you for not using any ("Purist") or for using all three ("Bag of Tricks"), so check the day's quests before you spend them.
Rating tiers
Every slot value has a color, and the leaderboards use the same scale:
| Tier | Rating |
|---|---|
| Grey | 64 and below |
| Bronze | 65 to 74 |
| Silver | 75 to 79 |
| Gold | 80 to 84 |
| Diamond | 85 and up |
| Legend (purple star) | A retired great, any rating |
Prime cards, legends and the over-99 scale
- Prime cards are a player's best-ever version. Boost applies them, and in several games they push past 99. Some games also stretch elite live ratings above 99 on purpose (Build a Baller stretches everything above 72, which is why its top builds run slot values of 111 to 122), and the OVR scale runs past 99 with them.
- Legends are retired greats with no current card, shown with a purple star. They only appear as legends when they are not already in the live pool.
- Over-99 values count fully toward OVR, but the career sim applies a soft cap above 99 so a 115 does not produce cartoon stats. It still helps, just less than linearly.
Hard Mode
The ☰ menu has a Hard Mode toggle that hides every rating while you draft. You assign on name recognition alone and only see the numbers when the build is done. It applies from your next build and is remembered per device. The "Flying Blind" quest (85+ OVR in Hard Mode) is one of the harder daily quests.
Step 4: Simulate the career
When every slot is filled you name your player, pick a team, and hit Simulate Career. The career plays out season by season from a rookie year to retirement: stat lines, awards, injuries (at most one per career), mid-career decisions, championships, then a verdict.
Two things to know about the sim:
- It is deterministic. The career is seeded from your build and picks. The same build always produces the same career, so there is nothing to re-roll and nothing to farm. If you want a different career, change the build.
- Every outcome traces back to slots. In the baseball games, strikeouts come from the Strikeout and Velocity slots, career length from Stamina and Frame, playoff success from Clutch. Each sport's guide on this wiki lists which slots drive which awards.
The verdict
Careers end in one of four halls: Hall of Fame (with a vote percentage and a "first ballot" line when earned), Hall of Pretty Good, Hall of Mid, and Hall of Not Good. Compilers who pile up counting stats without the peak get their own tag. As a rule of thumb across the sims, an 85 OVR build makes the Hall roughly 70% of the time, a 90 is close to a lock, and anything under 78 essentially never gets in.
After the sim you also get a Player comp: the real player whose slot profile is closest to your build, with a match percentage. A 99% match means you basically built a clone.
Step 5: Leaderboards, XP and the daily grind
- Daily boards reset at midnight UTC and show the top 200 for that day. All-time boards rank by OVR with no time filter. Your exact rank is pinned even if you are outside the top 200.
- Daily challenge: one seeded attempt per day, same cards for everyone in the world. See how the daily challenge works.
- XP: finishing a build earns 20 XP plus 1 per OVR point over 60; a career earns 40 XP, plus 150 for a Hall of Famer, plus 12 per ring. Levels climb through ranks from Rookie Ball to Immortal.
- Quests: three per day (Easy 75 XP, Medium 150, Hard 300, plus 150 for sweeping all three), same three for everyone worldwide.

Questions people ask
Is GoatLab free?
Yes. Every game is free in the browser, no download and no account needed. Optional extras are cosmetic or ad removal.
Why did my 99-overall player only add an 80?
Because a player only contributes the rating they have in the specific attribute slot you put them in, not their overall. Check the slot preview before you tap.
Can I re-roll a career I do not like?
No. Careers are deterministic: the same build always produces the same career. Change the build to change the outcome.
How many re-spins do I get?
In most games, one Re-spin, one Snag and one Boost per build. A few modes differ; the game shows the remaining count on the buttons.
What is a Prime card?
A player's best-ever special edition, with higher ratings than their current live card, sometimes above 99. The Boost power-up upgrades the landed player to their Prime.
What does Hard Mode change?
It hides all ratings while you draft. Nothing about the sim changes; you just build blind. It is remembered per device and starts on your next build.
