For the reason already mentioned the stakes should be so arranged that the
amount in the pool can always be divided by three. Thus, supposing that
three counters, or coins, are fixed as the amount for the deal, and six
for a loo, there cannot possibly be any surplus after the division among
the winners of the three tricks, no matter how many may have paid in.
If, however, the pool consists of such an amount as to render equal
division impossible, the division is made as nearly equal as can be,
and the winners of the first and second tricks have the preference.
It is not necessary that the loo should be twice the amount of the deal,
indeed any sum may be fixed for either the one or the other, and it is not
unusual when the deal is settled at 1 1/2d. for the loo to be 6d.,
or when the one is 6d. for the other to be 2s. 6d., and so on.
Another method is to make the stake for a loo unlimited, and yet another
to make it somewhat of a combination, unlimited up to a certain amount
(see Variations), but the more general course is to have a definite price
fixed (a) for the deal, (b) for an ordinary loo, and (c) for a single
loo, which latter is generally half the amount of the full loo.
Before commencing play in the game, it is desirable to settle
whether Club Law (see Variations) is to be enforced, and whether
any alteration is to be made in the law compelling the holder of
two or more trumps to lead the highest on the original lead.
The modification of this rule is "two or more trumps lead one."
