Along with your main XI, you pick 5 'reserves' when playing PlanetCricket's Fantasy Cricket. These players are only able to be used to totally replace one of your starting XI - and you can only make three replacements across the whole of a Fantasy Cricket competition. Once you put in a reserve, you cannot return to your original choice, and you can't choose a different reserve for that position. The replacements also need to be of the right type for the position you want to place them in - so a bowler can't replace a batsman. A good tactic might be to have a wicketkeeper and four all-rounders as your reserves, another could be a combination of wicketkeeper-batsmen and bowlers. In Fantasy Cricket games for a single match, you'll need to select them, but there won't be an opportunity to make changes. In short: There are 3 substitutions available in total across a FC competition You cannot undo a substitution You cannot replace a substitute with another one You need a substitute of the right type to replace a player Also note from the scoring system: If you have a question about substitutions/reserves, ask below!
