Should I use Fibonacci or T-shirt sizing?

Fibonacci (1, 2, 3, 5, 8, 13, 21) is the most common choice for planning poker because the increasing gaps between numbers reflect the growing uncertainty of larger tasks. T-shirt sizing (XS, S, M, L, XL) works well for high-level roadmap planning where you don't need precise numbers. This tool supports both.

How many players can join a planning poker session?

There's no hard limit, but planning poker works best with 3 to 9 people. That's usually the size of a scrum team. With more than 10 players, discussions after each round can take too long and slow down the session.

Can I connect this to Jira or other project tools?

This free tool is a standalone browser-based game. You can manually enter story titles and copy the final estimates into your project management tool. For direct integrations, you'd need a dedicated planning poker product with API connections.

Are the votes anonymous until reveal?

Yes. Nobody can see anyone else's card until the facilitator clicks reveal. This is a core part of how planning poker works. It prevents people from changing their vote to match a senior team member's estimate.

What happens if we can't agree on an estimate?

If the team is still split after two rounds of voting, a common approach is to go with the higher estimate or break the story into smaller pieces. The goal isn't perfect agreement; it's surfacing different perspectives so the team understands the work involved.

What is planning poker?

Planning poker is an agile estimation technique where team members use numbered cards to vote on how much effort a user story will take. Everyone reveals their card at the same time, which prevents anchoring bias and encourages honest estimates. If votes differ widely, the team discusses why and votes again until they reach consensus. It's one of the most popular ways scrum teams size their backlog.

How to Play Planning Poker Online

Create a room — Click the button above to start a new planning poker session. You'll get a shareable link.
Invite your team — Send the link to your teammates. Everyone joins from their own browser.
Select your cards — Read the user story, then each person picks a card value (Fibonacci sequence by default).
Reveal the votes — Once everyone has voted, flip the cards to see all estimates at once.
Discuss and re-vote — If estimates are far apart, talk through the differences and vote again until the team agrees.

The whole process keeps sprint planning focused and moving. Most teams can estimate a full backlog in under an hour.

Why Use Planning Poker for Estimation?

Get more accurate estimates. When everyone votes independently before seeing other answers, you avoid the loudest voice in the room setting the number. Research shows that group estimation with simultaneous reveal produces better results than open discussion.

Keep your team aligned. Planning poker forces a conversation when estimates don't match. That's where the real value is. A developer might see a task as simple while a tester spots edge cases that double the work. These discussions catch misunderstandings early.

Make sprint planning fun. Let's be honest, backlog grooming can drag. Turning estimation into a card game adds energy to the meeting and keeps people engaged instead of zoning out.
