<strong style={{ color:'#fff' }}>So geht's:</strong><br/>
Jeder Spieler startet in einer Ecke des 20×20 Rasters mit einem Startfeld.
Abwechselnd wählt jeder eine <strong style={{ color:'rgba(255,255,255,0.9)' }}>neutrale (graue) Zelle</strong>,
die direkt an sein eigenes Gebiet grenzt — oben, unten, links oder rechts.
Diese Zelle gehört dann ihm.
</p>
<p>
<strong style={{ color:'#fff' }}>Taktik:</strong><br/>
Breite dich schnell aus — aber pass auf: Wenn du deinen Gegner
<strong style={{ color:OPP_COLOR }}> einmauerst</strong>, kann er nicht mehr wachsen.
Blockieren ist genauso wichtig wie Expandieren!
</p>
<p>
<strong style={{ color:'#fff' }}>Ende:</strong><br/>
Wenn keine neutralen Felder mehr erreichbar sind, gewinnt wer
mehr Felder besitzt. Du bekommst eine <strong>Pushover-Benachrichtigung</strong>,
wenn du dran bist.
