1. Question

A player asked on Reddit about a situation on Duelingbook where their opponent continued playing without stopping long enough for them to read the cards being used.

The player explained that both players knew they had no response available, but they still wanted time to read the opponent’s cards and follow the plays to make sure everything being done was legal.

The concern was whether stopping the duel to read cards could itself be considered slow play, particularly when the player had already indicated that they had no response.

The question was essentially whether a player can pause the duel or call a judge when an opponent refuses to give reasonable time to read cards, even when there is no possible response to the current play.

2. Reddit Discussion

The discussion generally supported calling a judge when an opponent refuses to provide reasonable time to read cards or understand the ongoing game state.

One commenter advised simply calling a judge rather than allowing the opponent to continue without giving the necessary time.

Another commenter explained that making a judge call itself should not result in a penalty. They distinguished a gameplay-related judge call from situations where someone calls a judge for a non-gameplay issue and deliberately refuses to continue playing while waiting.

The same commenter considered the opponent refusing to provide proper response time to be a gameplay issue and stated that pausing the duel is appropriate in that situation.

Other comments focused on the distinction between having a response and having the right to understand what is happening. A player does not need to have an available response in order to read an opponent’s cards. The discussion also pointed out that priority still has to be passed to the player according to the game rules.

The final part of the discussion added an important qualification: the time spent reading should be reasonable. What constitutes reasonable reading time can vary depending on the situation and the players involved.

3. Summary of the Reddit Answer

Interpretation	Result
A player may need to stop the opponent to read cards	Yes, according to the Reddit discussion
Having no response removes the opportunity to read	No
A player can call a judge over the issue	Yes
Calling a judge automatically constitutes slow play	No
Reading time can be unlimited	No; the time should be reasonable
Priority can be skipped simply because a player has no response	No, according to the discussion

The Reddit discussion therefore treats reading an opponent’s cards as part of properly following the game rather than automatically as time-wasting.

The comments also suggest practical steps on Duelingbook: indicate that you need time to read, use the available communication tools to ask the opponent to wait, and call a judge if the opponent refuses.

4. Conclusion

The Reddit discussion indicates that reading an opponent’s cards is not automatically considered slow play simply because you have no response.

A player is still entitled to understand the cards being activated or otherwise publicly available and to follow the game state. The discussion also states that priority does not disappear merely because the player knows they cannot respond.

However, the discussion emphasizes that the amount of time spent reading should be reasonable. Excessive or unnecessary delays could raise a separate slow-play concern.

The Reddit answers are community guidance rather than an official Konami ruling. This discussion therefore documents how Reddit users, including commenters presenting themselves as experienced players, interpret the situation rather than establishing an official Duelingbook
