• Eight regular builds: AD Lethality, AD Crit / AS, AD On-Hit, AD Bruiser, AP Burst, AP Bruiser / DoT, Tank / Armor and Tank / Magic Resist. Each is a random three-item hand from that style.
• One Champ Build (the purple tile): your champion's current meta core, the three items players build first on them right now.
• The Suggested tile is always a regular build that fits your champion's class. Any tile is fair game.
• Hover an item (tap it on a phone) for its stats, effects and build path.

• Each regular build gets one ↺ reroll per round. The Champ Build gets none.
• ↺ Champion swaps your champion once per round. It doesn't eliminate them, it doesn't refund build rerolls you already spent, and the Champ Build switches to the new champion.
• Everything resets when the next round starts.

Rolled a champion you're not feeling? ⚔ Choose champion lets you pick anyone still alive in your pool instead. It's the mercy rule, and it costs you:

• It uses the round's one champion swap, same as ↺ Champion, and it's gone once you Lock In.
• Wins pay the same as before except the Champ Build, and losses cost more: On-role +1 / −2, Off-role +2 / −1, Champ Build +1 / −2.
• A loss still eliminates the champion. The tiles show the chosen pay the moment you pick, and the round is marked Chosen in your history.
• Rolled champions score exactly as they always have.

• A tile never repeats itself. A new roll shares at most one item with what that tile showed last round.
• A reroll shares no items with the hand it replaces.
• Hands come from shuffled bags, so a style works through most of its item list before items start repeating.

Riot gives each champion one or two classes (Sett is Fighter / Tank). A build is On-Role when either class fits it:

Assassin

AD Lethality, AP Burst

Marksman

AD Crit / AS

Fighter

AD Bruiser, AD On-Hit

Mage

AP Burst, AP Bruiser / DoT

Tank

Tank / Armor, Tank / Magic Resist

Support

No build of its own. Only a second class counts (Rakan is Support only, so every regular build is Off-Role for him)

Each round keeps the rules it was dealt under, so a rules update never changes a round you already rolled or a result already on the board.

• ✓ Win: only after you've finished all 3 items of the locked build. The champion stays in your pool.
• Won before finishing all 3? Don't report it. Play the same roll again.
• Once all 3 items are done, the build counts. If the game drags on, sell them and build what you need.
• ✗ Loss: the champion is eliminated, whatever build you played.
• Reports are final, and each locked build counts once.

• Pick up to 15 champions. The pool locks when the run starts.
• The run ends when every champion is eliminated, or when you end it.
• A new run resets the counters and keeps your history.
• The pop-out window keeps your three locked items on screen. Click an item to cross it off as you finish it.

• Open it from the gold Leaderboard tab at the top.
• Your best single run sets your spot. A new run only replaces it by scoring higher.
• Ranked by points, then completed builds. Ties share a rank.
• Results are self-reported. It's an honor system, not match verification.

• You can still roll, reroll, Lock In and browse the leaderboard.
• Saving results and appearing on the leaderboard take an account and an active run.
