One second before...? is a puzzle-style game for Android that turns watching online videos into a test of prediction. Each round presents a clip and asks the player to anticipate what happens next before the video reaches its climax.

Predicting the next event

The core activity is choosing the next event in a video. The description says players should watch for clues or hints in the footage that might signal what comes next, and it suggests going with a first instinct rather than overthinking the choice. These are the developer's suggestions for play, not a documented method for winning.

Videos and categories

The game includes 96 videos across eight categories. The description names animals, sports and disasters among them, and says the content is selected to appeal to a range of players. The video set is the main source of variety in the game.

Bonus rounds and rankings

Each category includes an extra round. According to the description, completing that round can earn bonus points that help raise a player's ranking. The source describes the ranking as the goal of the competitive side of play, but it does not explain how points are calculated beyond this.

Playing with friends

The description encourages players to compete with friends and compare who achieves the highest score or the quickest reactions. It presents this as a social challenge, but it does not describe the specific mechanics of how friend comparisons or rankings are shown.
