Coincheur's daily challenge
Updated
The daily challenge is one coinche situation a day, the same for everyone, with a single attempt. You choose your bid or your card, the coach scores you up to 3 stars and explains the best answer, then you share your result without giving anything away. It's free, with no account, on Coincheur's home screen.

How it works
The challenge is drawn from the date: on a given date, everyone gets exactly the same situation, with Coincheur's standard rules (no No Trump or All Trump). It changes at midnight, on your device's clock. You get a single attempt: once you have answered, the challenge is done for the day, and you come back the next day for the next one.
It sits on the home screen, just below “Play” and “Play with friends”, with your current streak. Open Coincheur and tap “Daily challenge”.
Three kinds of challenge
| Kind | What you see | What you decide |
|---|---|---|
| Bid | your hand and the bids made so far, or nothing if you open | a bid from 80 to 160 in a suit, or a pass |
| Opening lead | your hand and the contract, at the very first trick | the card that opens the deal |
| Move during the deal | your hand, the contract and any cards already played to the trick | the card to play |
From 2 November 2026, the three kinds rotate in blocks of three days: each comes back once per block, and never two days in a row. To get ready, go over how to evaluate your hand before bidding and how to choose your opening lead.
The score, from 1 to 3 stars
For a bid, the right answer is worth 3 stars (the right suit at the right level, or a pass when passing is right), and the right suit within 10 points is worth 2. When a hand is on the edge of an opening, passing or opening at 80 are both arguable: the other choice then earns 2 stars.
For a card, the coach simulates the rest of the deal for each possible card. Its card is worth 3 stars, but so is a card that does almost as well, within 5 points on average; up to a 20-point gap, it's 2 stars. The challenge is cleared from 2 stars. Either way, you see the best answer and the coach's explanation.
Your streak
Every day you play the challenge, cleared or not, your streak 🔥 goes up by 1. If you skip a day, it starts again at 1 with the next challenge. Your best streak stays displayed next to it.
The streak is saved in your browser: in private browsing, or on another device, it doesn't follow you.
Share without giving the answer away
The “📤 Share” button prepares a short message, like those of daily word games, to send to your friends:
Coincheur #127: 2/3 ✅✅⬜ 🔥5
coincheur.fr
It shows the challenge number (number 1 is dated 25 June 2026), your score as boxes and your streak. Never the card or the bid: your friends can try the same challenge without knowing the answer. If your device can share, its share sheet opens; otherwise, the text is copied.
After the challenge
The challenge takes a minute. To keep going on the same theme, the bidding and card-play drills offer situations of the same kind, as many as you like. To challenge a friend over a whole game rather than a single situation, finish a game against the AI and tap “🤝 Challenge a friend”: they will replay exactly the same deals as you (unless you played with cut-only dealing). Other questions about the app are answered in the Coincheur FAQ.
