Flash 10 (Pocket) board game. English-language

Flash 10 is a fast-paced card game for 2 to 5 players aged 8 and up, designed to test both quick mental arithmetic and reaction speed. Each player lays out ten cards face down in a row, then turns them over at the same time. Players then take cards from the spread-out pile in the centre and place them on their own rows, building stacks as quickly as they can.

The deck contains 120 cards: 100 number cards with values from 0 to 99, and 20 lightning cards that can be placed on any stack. As soon as a player has ten number cards in ascending order, they shout "Stop!" to end the round. Correctly sorted cards earn points, and the first player to reach 50 points wins the game.

A typical game lasts around 20 minutes. The rulebook is multilingual, while the cards themselves carry English text.
