📖 About TFT Rolling Odds Calculator
This advanced TFT Rolling Odds Calculator helps you make informed decisions when rolling for specific champions in Teamfight Tactics. Understanding rolling probabilities is crucial for optimizing your gold spending and increasing your chances of hitting the champions you need for your team composition.
Our calculator uses the exact champion pool sizes and rolling odds from Set 15, taking into account your level, the number of champions already taken from the shared pool, and advanced factors like other players' levels and game stage to provide the most accurate probability calculations available.
Whether you're trying to hit a key 3-cost carry at level 7 or fishing for 5-cost legendaries at level 9, this tool will help you understand exactly how much gold you should expect to spend and your chances of success.
🎯 How to Use the Rolling Odds Calculator
Step 1: Select your current level from the dropdown. Your level determines the base rolling odds for each champion cost tier.
Step 2: Choose the cost of the champion you're looking for (1-cost through 5-cost). Different cost champions have different pool sizes and appearance rates.
Step 3: Enter how many copies of your target champion have already been taken from the pool. This includes champions on other players' boards and benches. The shared pool has limited copies of each champion.
Step 4: Specify how many rolls you want to calculate odds for. This helps you plan your gold spending and understand your chances over multiple rolls.
Step 5: Use Advanced Options to account for other players' levels and game stage, which affect how many champions have been removed from the pool.
Step 6: Click "Calculate Rolling Odds" to see your exact probabilities, expected number of rolls needed, and estimated gold cost.

💡 Pro Tips for Rolling in TFT
🎯 Level Timing
Level 7 is optimal for rolling 3-cost champions (35% odds). Level 8 for 4-cost units (22% odds). Don't roll at level 6 for 4-cost units as the odds are only 5%.
💰 Gold Management
Only roll when you have enough gold to maintain economy interest. Generally, don't roll below 50 gold unless you're about to die or have a strong power spike opportunity.
🔄 Pool Tracking
Pay attention to what other players are building. If multiple players are contesting the same champions, your odds of hitting decrease significantly due to the shared champion pool.
⏰ Rolling Windows
Best times to roll: Stage 3-2 for 3-cost carries, Stage 4-1/4-2 for 4-cost units, and Stage 5+ for 5-cost legendaries. Rolling too early wastes gold on weak units.
🎲 Probability vs Reality
Remember that probability doesn't guarantee results. Even with 90% odds over 10 rolls, you might not hit. Always have backup plans and pivot strategies ready.
🔄 Rolling Strategy
Roll in chunks rather than one at a time. This helps you see your progress and make decisions about when to stop. Set a gold limit before you start rolling and stick to it.
❓ Frequently Asked Questions
Q: How accurate are these calculations?
A: Our calculator uses the exact odds and pool sizes from TFT Set 15. The calculations account for the shared champion pool and provide mathematically precise probabilities.
Q: Why do my in-game results differ from the calculated odds?
A: Probability describes long-term expectations, not guaranteed short-term results. You might get unlucky or lucky in individual games, but over many games, the odds will match the calculations.
Q: Should I always roll at the optimal level for my target champion?
A: Not necessarily. Consider your health, economy, board strength, and what other players are doing. Sometimes it's better to roll early to stabilize, even with suboptimal odds.
Q: How does the shared champion pool work?
A: All players draw from the same pool of champions. Each champion has a limited number of copies (usually 13-22 depending on cost). When someone takes a champion, it reduces the pool for everyone else.
Q: What's the difference between rolling odds and hitting a specific champion?
A: Rolling odds show the chance of seeing any champion of a specific cost. To hit a specific champion, divide the rolling odds by the number of unique champions of that cost, then account for pool size.
