use numbers twice
Use numbers in both a line AND a zone to get the best score. Get those Easter egg colors going.
Make Lots of Lines & Zones
Get as many individual lines and zones as you can. If you have the choice of lengthening a line or creating a line and a zone, it generally pays to create the line and zone. (Add up the two options to compare.)
Bonuses Only for BEST Line & Zone
Keep in mind, the majority of the Trek 12 playing boards only give bonuses for your SINGLE biggest zone and your SINGLE longest line.
