TFT Reroll Guide and Strategy Basics

Rerolling well in Teamfight Tactics is a balance between probability, economy, board strength, and lobby pressure. This guide explains the main ideas behind reroll decisions so the calculator results are easier to interpret.

1. Understand the shared champion pool

TFT champions come from a shared pool. When other players buy the same champion, fewer copies remain for everyone else. This is why scouting matters: the same roll-down can be reasonable in one lobby and risky in another.

• 1-cost units: Commonly used for early reroll compositions and hyper roll plans.
• 2-cost units: Often rolled around level 6 when a comp needs a 2-cost carry or key frontline.
• 3-cost units: Often rolled around level 7, especially for mid-game carry compositions.
• 4-cost and 5-cost units: Usually connected to level 8 or level 9 plans rather than early rerolling.

Exact pool sizes and shop odds can change across TFT sets or patches. Use the calculator as a planning tool and keep current patch information in mind.

2. Slow rolling

Slow rolling means staying above a gold threshold, often 50 gold, and spending only excess gold on rerolls. This keeps interest income high while giving you repeated chances to find your key units.

Slow rolling is most common when your board can survive without immediately spending all of your gold. It works best when you are not heavily contested and when your composition gains a lot from upgrading a specific 1-cost, 2-cost, or 3-cost unit.

3. Hyper rolling

Hyper rolling is a faster and riskier plan where you roll a large amount of gold early to hit important upgrades before the lobby outscales you. It is most often associated with 1-cost reroll compositions.

This approach can create a strong early and mid-game board, but missing key copies can leave you with low gold and limited flexibility. Before hyper rolling, check how many copies you already have and whether other players are contesting the same units.

4. Standard leveling and roll-down turns

Some boards are built around higher-cost carries, so they care more about reaching level 8 or 9 than rerolling early. In those games, you usually preserve economy, play the strongest board available, and spend gold on a planned roll-down turn.

A roll-down is not only about hitting a carry. You may also need frontline upgrades, trait activations, utility units, or a board that stabilizes your health total. The calculator can help estimate unit odds, but it cannot judge every tactical board decision.

5. Scouting and contested units

If another player is holding the same champion, your odds can become worse quickly. A unit being contested does not always mean you must pivot, but it does mean you should update your expectations.

• Count exact copies of your target champion when possible.
• Notice whether opponents are committed to the same carry or only holding temporary copies.
• Track your own health. A slow plan may be correct at high health and too slow at low health.
• Compare the cost of rolling with the value of leveling or adding a stronger unit.

6. When to stop rolling or pivot

A common mistake is rolling only because you have already invested in a unit. If you are low on gold, low on health, or heavily contested, it may be better to level, play a temporary upgrade, or pivot into a less contested line.

The calculator is useful here because it gives you a rough cost of continuing. If the expected cost is much higher than your available gold, that is a signal to reconsider the plan.

7. Reading probability without overreacting

A good probability does not guarantee success, and a low probability does not make success impossible. TFT is a game with variance, so the goal is not to remove randomness. The goal is to make better decisions over many games.

Use the calculator to compare options, sanity-check roll-downs, and learn from outcomes. It should support your decision-making, not replace scouting, positioning, item choices, and tempo judgment.
