Today’s challenge and friend challenges
The Cá Viên Chiên daily challenge gives everyone the same ready-made stall and the same customers, then compares scores. Play it on your own, send a friend a challenge link and see who makes more — your own stall is never touched.

What is today’s challenge?
Click “Today’s challenge” on the title screen. You play one trading day on a ready-made stall — with its own dishes, sauces, drinks and upgrades for its level — instead of your own. Everyone playing that day’s challenge meets the same stream of customers, arriving in the same sequence with the same orders. A customer who arrives when all 4 stools are taken is lost, so serving fast also keeps more customers.
The challenge card shows the stall’s day level, where it sells, the weather and how the score works. Type a name (used when you share a link) and click “Start challenge”.
How the Cá Viên Chiên challenge score works
Score = profit (in thousands of đồng) × 10 + the day’s average stars × 100. Profit is sales plus tips minus ingredients, drinks and rent. The score never drops below 0.
Example: a 120,000đ profit and 4.6 average stars → 120 × 10 + 4.6 × 100 = 1,660 points. Profit carries most of the weight; stars break ties between similar profits.
Why only the first try counts
Today’s challenge changes every day. The first time you click start on a given day is the attempt that counts; later ones are practice, and the summary says “Practice · counted score: …”.
Quitting midway or reloading the page still counts as your attempt, with 0 points — so play the first one to the end. A day’s challenge link still opens after midnight, and at most one day ahead.
Challenge a friend in Cá Viên Chiên with a link
When you finish, click “Challenge a friend”. The game makes a link with your name and counted score and opens the share sheet (or copies the link) for Zalo or Messenger.
Your friend opens it and sees “Sam scored 2350 — beat that!”, with the same stall and the same customers. When they finish, they click “Challenge a friend” to send their score back (for today’s challenge the link always carries their first attempt of the day).
The four ready-made stalls
A ready-made stall starts with full storage but cannot restock, so a burnt piece is gone for good.
- Alley corner · day 3 level: fish balls, beef balls, sausages, two sauces, kumquat tea.
- School gate · day 6 level: adds fried tofu, shrimp balls, spring rolls, tamarind, mayonnaise and milk tea.
- City park · day 9 level: adds cheese bread, crab sticks, squid balls, cheese sauce, plum sauce, herbal drink and lime tea.
- Night market · day 13 level: all 12 dishes, 6 sauces, 5 drinks and high upgrades (Fryer maxed, the rest at level 2).
Tips for a high score
- Mid heat is the safest: a burnt piece costs both the ingredient and the time.
- Only drop what customers are ordering; fried pieces nobody wants are a loss at closing.
- Serve while the patience bar is still green for a 20% tip and 5 stars — stars go straight into the score.
- Orders with a drink: start the drink as soon as the customer sits down, since each one takes a second or two.
Challenges: quick answers
Does a challenge change my own stall?
No. The challenge uses a ready-made stall; your own stall, money and milestones stay the same.
How is the score calculated?
Profit (in thousands of đồng) × 10 plus the day’s average stars × 100.
How do I send my score to a friend?
When you finish, click “Challenge a friend” and send the link with your name and score.
