Five rules that make Hundred markets price differently from T20
Most bettors arrive here from T20 and carry T20 instincts with them. The playing conditions are close enough to feel familiar and different enough to move the numbers, so it is worth being precise about what changes.
100 balls, not 120
An innings is 100 balls delivered in sets of five, with ends changing every ten. That is one sixth fewer deliveries than a T20 innings. Any total you have internalised from T20 cricket is therefore too high before you start, and the shortfall is not proportional either, because the balls removed are middle-innings balls rather than death overs. Match-total and team-total lines have to be read fresh rather than adjusted by feel.
Twenty balls per bowler, not twenty-four
Each bowler may send down a maximum of 20 balls, which is four five-ball sets, against 24 balls in a T20. A captain may use them as five or ten consecutively, their choice. Two consequences follow for bowler markets. A side needs at least five bowlers to complete an innings, so the fifth-bowler problem is sharper here than in T20. And a bowler's ceiling for a wicket market is lower, because there are simply fewer balls in which to take them.
A 25-ball powerplay with two fielders out
The first 25 balls of each innings are the powerplay, and only two fielders may stand outside the circle. After that the limit becomes five. In T20 terms the restriction runs for the equivalent of just over four overs rather than six, so the high-scoring phase is shorter. In-play prices that lean on an early run rate are extrapolating from a smaller and less representative sample than the same prices would in a T20.
A Super 5, not a Super Over
If a knockout match is tied, it is settled by a Super 5: each side faces five balls rather than six. It is a small difference until you are holding a tie-related bet, at which point the settlement rule matters. Check how a bookmaker words its tie and dead-heat terms for this competition specifically rather than assuming the T20 wording carries across.
Twenty-five balls makes a match
For a rain-affected game to produce a result, the side batting second must face at least 25 balls unless the match is decided sooner. That is a lower bar than most T20 competitions set, so a shortened Hundred match is more likely to stand and less likely to be voided. If your staking assumes a washout returns your money, that assumption is weaker here.
Two smaller conditions are worth carrying too. Each bowling side may take one 90-second strategic timeout, but not during the opening 25 balls. And a slow over-rate is punished by removing a fielder from outside the ring for the closing stage, which is a live in-play consideration rather than a footnote.
