TCG tournament calculator

Pick a game, enter the player count, then click your round-by-round results: get the rounds, the cut line and where you land on tiebreakers, all computed on your device.

How Tournament calculator works

The Tournament Calculator answers the two questions every trading card game player asks at an event: how is this tournament built, and where will I actually finish? Pick a game preset (Magic, Pokemon, Yu-Gi-Oh, Disney Lorcana, One Piece or Flesh and Blood) or a generic editable mode, enter the number of players, and it gives you the Swiss rounds, the top cut or qualifying invites, the Day 1 and Day 2 split for large Yu-Gi-Oh events, and the expected spread of records. Every figure is computed in your browser from each publisher's rulebook, so nothing you type is sent anywhere.

The standing section is where it gets useful and stays honest. Two players on the same record can land on opposite sides of the cut because of tiebreakers, mostly opponent match-win percentage, which depends on who they played. You click your result for each round, and the tool runs a Monte-Carlo simulation of the whole field with the selected game's real tiebreaker order to estimate where you finish. Because your real opponents are unknown, it reports a range and a probability, not a promise. The timing of your losses matters: losing in a late round usually means stronger opponents and a better tiebreaker, which is the gap between a good X-2 and a bad one.

How to use Tournament calculator, step by step

  1. Pick your game and format from the preset list, or choose Generic Swiss to edit every field yourself.
  2. Enter the number of players to read the Swiss rounds, the top cut or invite spots, the Day 1 and Day 2 split where it applies, and the expected field with the cut line drawn.
  3. For a Yu-Gi-Oh Regional, switch the territory between Europe and the Americas to apply the right invite table.
  4. In the standing section, click Win, Loss or Double loss for each round you have played.
  5. Open advanced options to set the typical double losses per round for no-draw games, which shifts the cut line.
  6. Press calculate to get your estimated final standing, whether you are a strong or weak finisher at your record, and your chance to make the cut or Day 2.

Common use cases

  • Working out before registration how many rounds a 240 player Regional will run so you can plan your day.
  • Deciding after Day 1 whether your 6-3 is a strong enough record to reach the Top 256 Day 2 cut at a large YCS.
  • Seeing why an X-2 that lost in the last round usually outranks an X-2 that lost in round one.
  • Checking whether your current record is likely inside the top cut or sitting on the bubble.
  • Estimating the qualifying line at a Yu-Gi-Oh Regional under the European one-invite-per-eight rule versus the Americas stepped table.

Frequently asked questions

How does the tool estimate where I finish?

It runs a Monte-Carlo simulation: it builds many random versions of the full field, pairs them in Swiss score brackets, and ranks everyone with the selected game's real tiebreakers, chiefly opponent match-win percentage. Your own results stay fixed to what you clicked, but your simulated opponents change each run, so the tool reports the spread of where you land rather than a single number.

Why does it ask for my result round by round instead of just my record?

Because tiebreakers depend on opponent strength, and in Swiss that is tied to when you lost. Losing in a late round means you were winning and faced strong opponents, which lifts your opponent match-win percentage. Two players at 6-3 can sit far apart in the standings, so the round-by-round input is what separates a good finish from a bad one at the same record.

Are the rounds, Day 2 and cut numbers official?

They follow each game's published rulebook. For Yu-Gi-Oh they match Tournament Policy version 2.5: Tier 1 and 2 events use the standard chart, while a YCS or WCQ adds rounds and splits into Day 1 and Day 2, so a field of 2049 or more plays 15 rounds with a Top 256 or 21 point Day 2 cut. Organisers can deviate for a specific event, so confirm anything decisive with your tournament organiser.

What is a double loss, and what does the double losses per round setting do?

In games with no draws, such as Yu-Gi-Oh since policy 2.5, a match with no winner is recorded as a loss for both players. A few of these happen each round and they pull players down the standings. The advanced setting lets you set the typical rate, which shifts the expected field and the cut line. It is usually a small share of matches.

Does the calculator send my record or player count to a server?

No. Every number is computed by JavaScript inside your browser tab. There is no upload, no account and no tracking of your inputs. You can put the page in airplane mode after it loads and the calculator keeps working.

Is this an official app from Konami, Wizards of the Coast or any publisher?

No. This is an unofficial planning tool and is not affiliated with, endorsed by or sponsored by Konami, Wizards of the Coast, The Pokemon Company, Ravensburger, Bandai or Legend Story Studios. Game names are used only so you can pick the matching ruleset.
