4 Main ways of getting claimblocks:

1. Playtime – You get 60 every hour, plus 100 you started off with
2. Money – /buyclaimblocks gets you 1 claimblock for $1. /sellclaimblocks gets you only $0.6 per claimblock
3. Donating as Kirn said – There is currently 15% off in the shop when you use the code spookysails
4. Winning BoTM prizes

If you’re having trouble claiming your whole area, here as some tips:

• Claim only important things – If you have sections of your base that don’t have any buildings in them, don’t claim them (or make two separate claims). Claim only what you are building, and avoid claiming in advance – as you’ll forget that you made the claims
• Avoid deleting claims, as you will lose 10% of the claimblocks within that claim.
• If you want to remove a large claim, make it very small first (9×9), then delete it to avoid losing lots of claimblocks
• Avoid claiming things for other people – its a bad habit for me, and you save yourself a lot of claimblocks
• Don’t claim random stuff you find lying around. Found a nice build somewhere? Think; is it close enough to my base (so that it doesn’t require another sethome), is it in a good condition, and do I really need it. If the answer to any of those is no, sell it for a couple of bucks, or make a forum post, don’t waste claimblocks
• /claimslist – tells you the coordinates of all of your claims. If you see a random claim somewhere that you forgot about, delete it
• Good way of making money; Sell and build ships for others, or sell grinders
