How Big Two scoring works

Big Two is played by four people with 13 cards each. The hand ends as soon as one player runs out of cards. Everyone else counts the cards they still hold, and that count becomes their card points:

card points = cards left × multiplier (× 2 if you are still holding a 2, where that rule is on)

The multiplier depends on where you play. MejaPop ships four presets:

PresetMultipliersHeld 2Tips shown
Big 2 · Malaysia / Singapore10–12 cards ×2, 13 cards ×3off♦3 leads; agree the suit order first
Chor Dai Di · Hong Kong8–9 ×2, 10–12 ×3, 13 ×4♠2 doubles♦3 leads; ♠ > ♥ > ♣ > ♦
Pusoy Dos · Philippines10–12 ×2, 13 ×3off♣3 leads; ♦ > ♥ > ♠ > ♣
Capsa Banting · Indonesia10–12 ×2, 13 ×3off♦3 leads; quads or a straight flush can beat a 2

By default the table then settles pairwise: every two players compare card points and the difference moves between them, so the four results always add up to zero.

Example with the Malaysia / Singapore preset: cards left 5 / 8 / 0 / 12 give card points 5 / 8 / 0 / 24, and the round ends +17 / +5 / +37 / −59.

Keep score in three steps

  1. Pick a preset, add 3–4 players and set the base points.
  2. After each hand, tap who went out, then tap how many cards everyone else has left.
  3. Check the round preview (+/− for each player) and save. The leaderboard and trend chart update straight away, and at the end you can make a share image for the group chat.

House rules you can change before you start

  • The multiplier table (for example 8 cards ×2 instead of 10).
  • Held 2 doubles: on or off, ♠2 only or any 2.
  • Settlement: pairwise difference, or other players give their card points to the winner.
  • Base points.

Rules are locked once the session starts, so nobody can change them halfway through. Mistakes can be edited, deleted or undone, and every change is kept in the history.

FAQ

What is the difference between Big Two, Chor Dai Di and Pusoy Dos?

They are the same climbing game with local names. The lead card, suit order and multipliers differ, which is why MejaPop has a preset for each region.

Does the suit order change the score?

No. Suit order and who leads are shown as tips only. The score depends on cards left, the multiplier table and the held-2 rule.

Can three people play?

Yes, 3 or 4 players. For now each player can have at most 13 cards left.

What if I enter a hand wrong?

Edit, delete or undo it. Totals are recalculated and the old version stays in the history.

Do I need to install an app or create an account?

No. It runs in the browser, works offline after the first visit, and your data stays on your phone. You can add it to your home screen.
