I'm guessing - don't play, don't lose!
No need to guess, it's the only system which guarantees no loss!
(also guarantees no win, but given the odds it's a successful system).
I've also seen systems which work on the select one ball method ( or [broken link removed]).
In theory it seems ok (at a very quick first glance), but only when you don't investigate it. A little thought and you can see that the risks are just crazy!
[I'll give a few details as I know a few out there will like looking at the theory. Please, don't look at this as some gambling advice, I'm saying it as I've heard it and found it amusing to analyse. I'm sharing it as I assume others might do the same. The potential losses are exponentially more than the potential gains!!!]
Having a quick look through the Lotto page above the "prize limits" seem to have ended this being a runner. Maximum payouts as a total (€2million max, split between all winners) mean that even if the pool is large enough to keep the bet going, the payout may not match the total paid out to date.
The seem a little more open to abuse regarding the working as a syndicate (it's illegal to do, so huge risks involved) so it could possibly be done there, but again, the losses you could make mean the profits would be wiped out and leave anyone involved hit hard in the pocket!
Basic idea.....
Pick one number (I've heard of people picking the number which hadn't come up in the longest time, but as all balls have an equal odds of coming up in independant draws this seems a bit of a waste of effort).
Back it using a "select one number game"
(two listed above, I'll go with Lotto54321 for the calculations as the 4/1 odds [bet one, win five - seems to be 4-1] are lower than the 11/2 of PP [I'd assume that means bet one, win six fifty (11/2 odds plus stake back)]. Whatever the odds the same idea holds. It just means you'll stack up your losses a lot faster as you keep "chasing" them.
Then you must "chase" the loss (probably the biggest mistake of most gamblers/investors).
If you bet €1 as your first bet, in order to keep your (potential) profit static you must increase your bet by 25% (odds of 4/1 so a 25% increase in stake gives back the loss to date) [to make the system work (even in theory) you'd have to increase by more than this so your potential profit grows as your timeframe of investment..... I shudder to use that word in this context but I really am using it in the loosest terms.... grows. For the sake of a few sample figures lets say we go with 1.5 as the iteration.
So, we now bet €1 on the first weekend draw, €1.50 (€1*1.5) on the wednesday draw, €2.25 (€1.50*1.5) on the next... and so on.
Each time we increase the bet we increase the (again, I shudder calling this profit but for the sake of argument) profit slightly. A more agressive approach (double each bet or 2.5 times the previous bet) would give a higher profit faster, but mean a bigger starting pot/fund would be needed.
A sample short table of Bet, Cost, Win and Profit can easily be drawn up in Excel...
First column bet. Start with 1 and for the rest of this column make it the previous cell*1.5.
Second column cost. This is equal to bet for the first cell and equal to bet+previous cost for all additional cells.
Third column win. Bet*5 for the Lotto54321 odds.
Fourth column profit. Win - cost.
(Did try and throw in the table for illustration but formatting didn't quite work out)
You can run it for as far as you'd wish to consider.
So, after four weeks (2 draws per week) just less than €50 has been bet (in total). If you get lucky on the fourth week (8th draw) you may win €36 profit, or else you (have to) keep chasing and the potential costs get quick fast.
After two months it's over €1300 (potential profit €877) and after three months it's €33666 (potential profit €22447). You can imagine just how bad it could get (not to mention the difficulty in placing bets this large and the legal side of it).
It's basically the same idea as someone walking into Vegas and betting bigger and bigger (technically not able to do it anymore with table limits) on red until finally they finish up......
the martingale system... plenty of broke gamblers around to prove it doesn't work.
Just wanted to throw it up incase anyone had an interest in thinking about it, I know it passed a few days in maths lectures for myself and some friends not too long ago.
