Before you start, Open TT explains the game: a ladder is a living ranking where you challenge those above you and, if you win, you climb. Create one for your club or your usual playing spot and let nearby players join in.
Onboarding
What is a ladder?

A competition born from your community.

Just finished a match, friendly or official? Scan your opponent's QR, pick the format (best of 3, 5 or 7) and enter the result. No paperwork, no friction: it's logged in seconds.
Express Registration

Members

Your community, ranked by position.

Active, sent, received and history: organise your challenges into tabs, with clear deadlines and the option to cancel while they're still pending.
Challenges
Manage your 1v1 duels

All your challenges, in one place.

When someone challenges you, you know right away. Notifications and the received-challenges counter prompt you to respond in time.
Home
Challenges received

You've been challenged. Respond.

As the organiser, you arrange the starting positions (manually or by Elo) and activate the ladder. From then on, only challenge results move the ladder.

Set the players and kick off.

View the full ladder with your position highlighted and who you can challenge based on the configured range. Launching a challenge is just one button away.

The app shows only the eligible opponents based on your position and the ladder's range. Challenge whoever is above you and go for their spot.
Ladder
Launch a challenge

Choose who you want to beat.

Before sending the challenge, the app spells out the rules: winning means taking your opponent's spot. Transparent rules, no surprises.
Ladder
Confirm the challenge

Win and you swap positions.

Ladder challenges show origin, destination and expiry date. Change your mind? You can cancel while it's still pending.
Challenges
Pending

Every challenge, with its deadline.

Clear, actionable notifications: they alert you to a new ladder challenge or a change in position, with a direct button to respond.
Notifications
Challenge received

Never miss a challenge.

When you respond you see who's challenging you, the positions at stake and the deadline. The app reminds you that rejecting too often drops you down rungs: every choice counts.
Challenge
Respond

Accept the challenge or face the consequences.

Once the challenge is accepted, you have your opponent's contact to arrange a meet-up and a button to start the match when you're at the table.
Challenge
Accepted, ready to play

Challenge accepted: hit the table.

Before starting you define the match format. Both players share the same configuration, and the result will require the opponent's confirmation to be official.
Match
Set the format

Both players, the same rules.

Record the result of each game as you play. The app keeps the overall score and saves the history of games played in real time.
Match
Live scoreboard

Log the score game by game.

When a player reaches the required number of games, the app alerts you and invites you to finish and register the official result.
Match
Finish

Match closed, result ready.

When your opponent logs the score, you get a notification to review and confirm it. Only then does the result become official: fair play guaranteed.
Notifications
Confirm the result

Results both players validate.

Before it's made official, you review the score game by game and the winner. If something's off, you can reject it. Double confirmation, zero disputes.
Result
Confirm the result

Review, confirm or reject.

Result confirmed and positions updated automatically: the winner climbs, the opponent drops. The ladder stays up to date effortlessly.
Ladder
Challenge completed

The ladder reorders itself.

Your Elo evolves with every result, with a detailed history of variations, opponents and category. It doesn't decay through inactivity: your progress is yours.
