<b>Game of Differences</b> <br>
Challenge your opponent to a game of differences! Players play in turns.
<ul>
<li>The first player chooses a number and presses <i>Ready</i>.</li>
<li>The second player chooses two numbers that differ by the number from the first player and presses <i>Ready</i>. If the equation is correct, the second player gets a point.</li>
<li>The second player chooses a number for the first player and presses <i>Ready</i>. Then the first player finds two numbers to complete the equation.</li>
<li>If there are no numbers available that would complete the difference, the player presses <i>Pass</i>.</li>
</ul>
If one player has no numbers left or if both players pass, the game is finished.
The winner is the player with most points.<br/>
<br/><br/>

<b>Subtraktions-Wettkampf</b> <br>
Fordere Deinen Gegner zu einem Differenzenwettkampf heraus! Die Spieler spielen abwechselnd.
<ul>
<li>Der erste Spieler wählt eine Zahl und drückt <i>Fertig</i>.</li>
<li>Der zweite Spiele wählt zwei Zahlen, deren Differenz die Zahl des ersten Spielers ergibt und drückt <i>Fertig</i>. Wenn die Gleichung korrekt ist, bekommt der zweite Spieler einen Punkt.</li>
<li>Der zweite Spieler wählt eine Zahl und drückt <i>Fertig</i>. Dann wählt der erste Spieler zwei Zahlen, die die Gleichung vervollständigen.</li>
<li>Wenn es keine passenden Zahlen mehr gibt, drückt der Spieler <i>Passe</i>.</li>
</ul>
Wenn ein Spieler keine Karten mehr hat, oder wenn beide Spieler hintereinander passen, ist das Spiel beendet. Sieger ist der Spieler mit den meisten Punkten.<br/>
<br/><br/>
Wenn Du nur einen Namen einträgst, spielst Du alleine. Versuche so geschickt zu spielen, daß Du alle Karten aufbrauchst ohne zu passen.
