OFFICIAL CTWC MAIN EVENT RULES

(Click here to read the Official CTWC Regional Tournament Rules).

NES Rules   Format:  8-bit Nintendo Tetris (not Tengen).

(**starred sections and items in bold indicate rule changes for 2019.)

A group of NES consoles, NES Tetris carts, and NES controllers will be provided for competitors to play. Competitors can use the provided NES controller or bring their own controller. The controller can be any standard unmodified* original NES controller, any standard unmodified original NES “dog bone” style controller, or any standard unmodified “Goofy Foot” style controller. Tournament or CTWC officials may disqualify any controller other than those listed here (including but not limited to other 3rd party controllers, controllers with turbo features, etc), and any games played with those controllers, at any time.

*Any additional electronics will result in automatic disqualification. Controller maintenance (cleaning, swapping D-pads or buttons with original NES controller replacement parts, etc) is allowed and in most cases will not result in a disqualification. Any modifications may be evaluated by the tournament or CTWC officials and may result in a disqualification.

Qualifying Round (Saturday, Oct. 19th)

  • **The Qualifying Round will determine the seeding of a 48-player tournament bracket.
  • Entry fee is $20. Once paid, entrants can make as many qualifying attempts as they are willing to stand in line for. NES stations will be available to rent for one period of one hour for an additional fee (for more info, see NEW RULES below).
  • Qualifying round will be held on Saturday in the free-play area from 10AM-3:45PM (“last game” will abe announced at 3:45PM, and all games in progress may be completed at that time).
  • Qualifying attempts will be on type A Tetris for highest score starting on level 9 or higher.
  • Once an entrant’s game is over for any reason, they must make sure their score is recorded by a scorekeeper and then return to the back of the line for another attempt.
  • Note: CTWC-approved Qualifying Events are held around the world in the year preceding the CTWC (see Schedule). The winners of these events may automatically qualify for placement in the bracket if the following conditions are met: 1) The Qualifying Event must be a NTSC NES Tetris competition, and 2) The winner must have qualified at the Qualifying Event with a score of 700,000 or above.
  • Qualifying Event winners who meet the above criteria are “Auto Qualifiers”.
  • In the unlikely event that an Auto Qualifier is unable to achieve a top 48 score during the Qualifying Round, they will be automatically seeded at the bottom of the bracket, displacing any players in those positions.
  • **From 4:30-7PM, seeds 17-48 will compete in a “Round Zero” to advance to the 32-player tournament bracket Main Event on Sunday. Here’s the bracket we’ll be using. Matches will follow the same rules as Round 1 (see below).

MAIN EVENT (Sunday, Oct. 20th)

The tournament will continue on Sunday morning with a five-round, 32-player seeded tournament bracket based on the results of qualifying and the winners of Round Zero.

  1. Each match in Rounds 1 and 2 consists of up to 3 games. First player to win 2 games wins the match and proceeds to the next round. **All matches in rounds 3-5 (top 8) will be first to win 3 games (best 3 out of 5).
  2. The higher-seeded player in each match will choose the starting level of 15 or 18 for game 1. The lower seed will choose for game 2, and if necessary, the higher seed will choose for game 3. (Starting level during rounds 2-5 will always be 18).
  3. Once the starting level is chosen, the ref will roll dice to determine the piece sequence.
  4. The players will set their games to the rolled sequence and the agreed upon level and push start simultaneously at the prompt of the referee. Referees will settle any disputes.
  5. The player with the highest score wins. If one player tops-out and the other player already has a higher score, the game is finished. If one player tops-out and the other player has a lower score, that player will continue until they either top-out (having lost) or exceed the other player’s score, winning the game.
  6. **If a NES console or TV freezes, loses power, or otherwise becomes unplayable, both players will be stopped by the judge and the games will be reviewed. Considering the scores, line counts, and piece stacks of each player at the time of the malfunction, along with any other circumstances deemed relevant, tournament officials will decide to either have players replay the game or, in cases where a player is deemed to have an insurmountable lead,  award a win to the player who had the higher score at the time the malfunction occurred.
  7. **If a NES console or TV experiences a momentary glitch, interference, or visual disruption, the affected player must attempt to make the judge aware of the problem and must keep playing to the best of their ability. After both players have topped out, the affected player may request an official review. This is the only time a review can be requested. If a review is not requested, the results of the game will be accepted and can’t be subsequently changed for any reason. If a review is requested, considering the scores, line counts, and piece stacks of each player at the time of the malfunction, along with any other circumstances deemed relevant, tournament officials will decide to either accept the results of the game or have players replay the game. Under no circumstances will a win be awarded to a player who was trailing at the conclusion of the game.

**The Finals (Round 5) will begin at 5pm PST. The winner of round 5 is the Classic Tetris World Champion.

PRIZES:

1st: $3000

2nd: $1500

3rd-4th: $750

5th-8th: $500

9th-16th: $250

RENTAL STATIONS

SIGN-UP SHEET

This year there will be 12 NES stations available for blocks of uninterrupted qualifying attempts. Each player has the option to reserve one station for one hour for an additional fee of $20. More Rental Stations may be made available on the day of the tournament.

Players who choose to rent stations may also stand in line for additional attempts throughout the rest of the Saturday qualifiers.

Sign-ups for rental stations will begin on Monday, October 14th at noon Pacific time.  Visit the sign-up sheet to reserve your spot.

QUALIFYING MAX-OUTS

In the event of multiple max-outs during qualifiers, those seeding ties will be broken by 2nd best score of the day. If multiple players score 2 max-outs, ties will be broken by 3rd highest score of the day, and so on. (This rule also applies to the rare occurrence of a tie that is not a max-out.)

New Rankings Calculation Method (NES)

There is a slight change in the Final Rankings Method.  Final Rankings will now be determined by, in order of importance, 1.) round advanced to, 2.) games won in losing match, 3.) combined score of the two losing scores in the losing match.  (this eliminates the possibility of being penalized for winning a game with a very low score)

Official CTWC Regional Tournament Rules

Note: Schedule and Official Rules MUST be posted in an easy-to-find section of the hosting events website.

CTWC Regional Tournaments are played in 4 rounds:

  1. Qualifying Round
  2. Top 8 Round
  3. Semi-Final (Top 4) Round
  4. Final Round

Qualifying Round

During this round, competitors will play NES Tetris A-Type and try to get the highest score possible. The qualifying round will run for a period of time that will be clearly posted at the tournament venue. At the end of the qualifying round, players with the top 8 scores* will advance to the Top 8 round.

A designated group of NES machines will be used for the Qualifying Round. Players should line up, wait until they reach the front of the line, then take their place at one of the available NES consoles and start their game.

Each player is allowed to play a single game, starting on level 9 or higher. There is no “warm up” time allowed on the machines provided for the Qualifying Round. If a player starts on a level below 9, they will have one opportunity to reset the game and start on level 9 or higher.

When the player’s game is over, they can choose to submit their score to a tournament official or leave the score unrecorded. If they wish to submit their score, they should raise their hand to get the attention of a tournament official. The tournament official will then record their name and score. If the player wants to play another game, they must return to the back of the line.

* If two or more players have identical scores, (as may be the case with multiple players achieving the maximum score of 999,999) then the players’ 2nd-highest scores (and 3rd-highest, 4th highest, and so on as necessary) will be used to determine their positions on the leaderboard. Only officially submitted scores will be considered for tie-breaking purposes. Players must officially submit, at the time the score is achieved, any score that they want to be considered in the calculation of the official leaderboard ranking.

Top 8 Round, Semi-Final (Top 4) Round, and Final Round

Using the scores obtained during the Qualifying Round, the top 8 players are seeded in a single elimination tournament bracket as follows:

The remaining rounds consist of two player NES Tetris A-Type matches. Before the first game of each match, players will be given 1-2 minutes of “warm up” time. After the warm up time, the player with the higher seed will choose the starting level. The standard available starting level options for CTWC events are typically 15 and 18*. After the first game, players take turns choosing the starting level. When the players are ready, a tournament official will issue a 3-2-1 countdown, at which point the players will simultaneously begin their game by pressing start on their controller. Game play will continue until one of the following scenarios occurs:

  1. both players have topped out
  2. one player has topped out and the other player has a higher score

In either scenario, the player with the highest score wins the game. If both players obtain the maximum score of 999,999, the game will be replayed.

*Some Regional tournaments may allow players to start on levels as low as 9, depending on the anticipated skill level of the competitors and time available. Tournament officials will make this known at the tournament venue in advance.

Top 8 Round and Semi-Final (Top 4) Round Matches

These matches are best-of-3. The first player to win 2 games will advance to the next round.

Final Round Matches

The final match is best-of-5. The first player to win 3 games wins the tournament.

Equipment and Controllers

A group of NES consoles, NES Tetris carts, and NES controllers will be provided for competitors to play. Competitors can use the provided NES controller or bring their own controller. The controller can be any standard unmodified* original NES controller, any standard unmodified original NES “dog bone” style controller, or any standard unmodified “Goofy Foot” style controller. Tournament or CTWC officials may disqualify any controller other than those listed here (including but not limited to other 3rd party controllers, controllers with turbo features, etc), and any games played with those controllers, at any time.

*Any additional electronics will result in automatic disqualification. Controller maintenance (cleaning, swapping D-pads or buttons with original NES controller replacement parts, etc) is allowed and in most cases will not result in a disqualification. Any modifications may be evaluated by the tournament or CTWC officials and may result in a disqualification.
