2 Innings of 25 Overs Each
In order to gain popularity among the audience, ODI format can be transformed into Test Cricket Style with two innings of 25 overs are to be played. The team batting first will have 25 overs and then the other team will bat for 25 overs and then just like in Test matches, there is a second innings of 25 overs each but the most interesting point is, throughout the match you have only ten wickets. The team who score more in the first innings has a lead and then the other team has to chase it down.
To make the match more interesting, the players who batted in the first innings will not bat in the second innings and the bowlers will have a quota of only 8 overs in both innings which he can use it anyhow.
