Question 1

What does "reroll" actually mean — the button I press, or a type of comp?

Accepted Answer

Both. Players use the same word for two different things.

The action is the shop refresh. You spend 2 gold (default hotkey D) to discard the visible champion shop. The shop then draws a new five-slot row from the shared champion pool.

A "reroll comp" is a strategy built around that action. You deliberately stay at a lower player level, so the shop's odds skew toward the cost tier your carries live in. Then you roll a lot to find the nine copies needed for a 3-star.

Note: Every comp uses the action. Only some comps are reroll comps.

Question 2

Why does staying at a lower level help a reroll comp?

Accepted Answer

Because each player level has a fixed shop-odds table. That table shifts probability toward higher-cost tiers as you climb.

At level 5 the shop odds are roughly as follows.

45% cost-1.
33% cost-2.
20% cost-3.
2% cost-4.

At level 7, cost-1 odds collapse to 19%, while cost-3 climbs to about 40%.

If your carry is a cost-1, every level-up you take cuts your odds of seeing it. So you stay at level 5 for cost-1 carries, 6 for cost-2 carries, and 7 for cost-3. That is what makes "rolling a lot" actually find the nine copies you need.

Question 3

What's the difference between hyper-rolling and slow-rolling?

Accepted Answer

Both are ways to play a reroll comp. They differ in tempo and risk.

Hyper-rolling means dumping nearly all your gold in one window to hit your 3-stars in one big turn.
That window is often Stage 3-1, rolling down to about 20 gold or even 0.
Slow-rolling means rolling only your excess above 50 gold each round, so interest income stays maxed.
You then hit upgrades gradually over many rounds.

Note: Slow-roll is more consistent and lets you pivot if the comp does not land. Hyper-roll spikes harder when it works, but leaves you broke if it does not.

Question 4

Is "Hyper Roll" the strategy or the separate game mode?

Accepted Answer

Both. It is a real source of confusion.

Hyper-rolling started as a strategy name: spend everything in one window to chase 3-stars. Riot then shipped a dedicated lab mode called Hyper Roll, named after that strategy.

The mode is its own thing.

Starting Health is 20, not 100.
There is no gold interest.
Your level auto-advances each stage instead of being bought.
Damage per loss scales by stage.

Note: Talk of "hyper-rolling" in standard ranked refers to the strategy. The mode lives behind a separate queue.

Question 5

How does the shared champion pool affect my odds when I reroll?

Accepted Answer

All eight players draw from the same finite pool.

The pool sizes are roughly as follows.

30 copies of each cost-1 champion.
25 copies of each cost-2.
18 copies of each cost-3.
10 copies of each cost-4.
9 copies of each cost-5.

Every copy held on someone's board or bench is removed from the pool. When one opponent contests your cost-1 carry, you each effectively split about 30 copies. A 3-star (9 copies) becomes much harder to assemble for both of you.

Note: Reroll comps benefit structurally from large pools. That is why cost-1 reroll is the most reliable variant and cost-3 reroll is the hardest.

Question 6

When should I stop rolling for a 3-star and just level up?

Accepted Answer

When the math, and the lobby, stop favoring you.

Guides cite three trigger points.

You have already hit the 3-stars you needed, and rolling further is throwing gold at a coin flip.
You have bled past roughly 30 Health and need a level-8 board to stop losing rounds.
Your carry is heavily contested, and a 3-star is no longer realistic.

The principle: a reroll comp's power spike is conditional on hitting. If you are not hitting and you are getting hit, level up. Leveling buys you new units, and bigger boards, faster than more rolling buys you 3-stars.

Question 7

Why is cost-3 reroll harder than cost-1 reroll?

Accepted Answer

Two compounding reasons: a smaller pool, and a more expensive level.

The pool is smaller: 18 copies of each cost-3 against 30 of each cost-1.
So any contestation hurts more.
Cost-3 odds peak at level 7, at about 40%.
But reaching level 7 means paying steep XP costs (XP means experience points), and your gold-roll value is lower.
Cost-1 reroll comps thrive at the cheaper level 5, with 45% cost-1 odds.

Note: Cost-3 reroll generally requires you to be ahead on Health, or already holding several natural copies, before committing. It is more of a "top-half" specialization than a beginner-safe baseline.

Question 8

Does the shop reroll for free between rounds, and what about "free reroll" effects?

Accepted Answer

Yes. The champion shop automatically refreshes once at the start of every round, at no cost. Beyond that, every reroll you trigger manually costs 2 gold.

Some augments and items in the current set's catalog grant additional free shop refreshes on top of the round-start one. Those are entity-specific and rotate per set. Check this page's entity list for the live patch's free-reroll sources.

Note: The free round-start refresh itself is a permanent base-game rule. It is not patch-volatile.
