Cards lie scattered on the table. Type them in order: the smallest number, the first word in the alphabet or the earliest event first. You pick a card just by typing it — the cards that still match what you have typed light up, and a card is placed the moment you finish it. A card typed too early is not wrong, just not yet: it bounces back to the table and costs a life. In Timeline it also shows its year. Backspace lets you change your mind before the card is finished. Every round has more cards; a round without a single bounce earns a bonus, and so does a fast one. Numbers: later rounds bring negatives, decimals and fractions — compare them by value. Alphabet: the order of your own language’s alphabet. Timeline: the year appears once the card is in place. You have 3 lives.
