Here's a new game. Darts, using only the Bitcoin protocol. (Anyone done this before??)How to Play
In this game, the bullseye is the end
of a specific Bitcoin block. The dartboard is a bitcoin address.
Everyone uses their Bitcoin client to attempt to "hit" that block.
The bottom of the Bitcoin client shows what block you're on:http://i.imm.io/6MMp.png
So, say, for example, we selected block 133082 as the target. When it says "133081 blocks" there, that means block 133081 is finished on the network. So now you send your bid to the address of the dartboard, hoping to hit the last part of the next block: 133082. It's all about guessing when the network is going to finish that block. Sometimes a block is done in fifteen minutes. Other times it's three minutes. No one knows!
If you miss block 133082 (by being too early or too late), then your bid goes into the pot. Keep in mind that some blocks are extremely short and only contain one transaction!
Darts are scored in the order they appear on blockexplorer. Game is tallied after 2 confirmations (the target block and the block after that.)About the CoinTricks series
I'm more interested in the protocol hacks that make these games possible, so I don't charge any fees for this game. I have a few other games I've designed which are more complex, depending on how this one does.SECOND ROUND: TIP OF THE TAIL.
This time, we're shooting for the end of the block.
In this round, everyone bids 0.1 BTC. Anything above or below will be returned. The bottom half of those who hit the block all win.
The winner takes half the pot. Second place takes half of what remains. Third, half of that. Until the top half is paid. The last person gets what's left, minus transaction fees.
If there is an uneven number of players, the middle player is still in the winner's circle. (This way two will win if only three hit.)
If there is only one winner, this person counts as 2nd, 3rd, 4th, etc. Meaning the pot is theirs.
No winners and I'll return your tenths of a coin.TIPS
Send from the Bitcoin client! Do not send from a website. I will use your return address to send back the winnings.
Start up the client at least five or six blocks in advance. Your client needs to be up-to-date with the blockchain!
Also: donation bids. If you like what I'm doing with these games, send a bid of 0.09 BTC instead of 0.1 BTC. I will chip in the extra 0.01 BTC and, if you win, 20% of your return will go toward my project 'coinsplit'. I need some real BTC to test with and to do some coinsplitting games with.http://forum.bitcoin.org/index.php?topic=20252.0ARCHIVES
