## What is Softball DP/Flex Simulator?

Introducing the first and only DP/Flex Softball Simulator. This app is designed to help you fully understand the interworkings of the DP/Flex rule, per the official rulebook (collegiate, high school, club, & international).

Enter line-ups and make substitutions which the app will confirm are allowed (or not allowed) before you take the field, so that you can be prepared & confident when it comes to game time.

-Create your own line-up with custom player names

-Prep for games by running your substitutions through this app (or use in the dugouts, where allowed)

-Save your line-ups for future use

-Access to videos, such as why it's advantageous to enter your DP into the field and create an OP

This app follows the basic premises of the DP/Flex Rules:

-Flex is always listed 10th on the lineup card, and can only enter as a batter if for the DP.

-To use a DP/Flex, must start the game with a DP/ Flex (cannot add once the game starts).

-Once any player leaves the game (out of the lineup), they have used a sub. Only starters may re-enter (one time) after being subbed out. Thus, if flex bats for DP, this counts as a sub for the player in the DP spot.

-The DP spot is initially listed as only hitting, however they can enter the field and play a position, turning the player they entered into the field for, into the "OP" (Offensive Player), who now just hits. The flex cannot hit for the OP, still can only hit for the DP.

### 5/5 — Great tool!

*2026-06-05*

Great tool for learning, teaching or verifying potential changes using the Flex/DP rule. Updated to work with both single and double re-entry rule sets.

### 5/5 — Eh

*2026-05-15*

Can you add an EH to lineup when you have a DP/flex?

**Developer response:** No- some tournaments or organizations allow that, but this app is designed to follow the "standard" rulebook of 10 maximum starters (which would be a DP & Flex).  You can however create an "OP," offensive player, by entering your DP into a fielding position.  This is allowed in the app and also covered in the strategy/videos section of the app on how to do this, and why you'd want to

### 5/5 — Great Competitive Tool

*2026-02-24*

This app really helps optimize our lineup to help us be as competitive as possible while keeping it simple and straight forward. Our staff will talk through various lineups and run them through the simulator prior to competition.
