Random Deals

The Practice app supports two ways of dealing random hands. Each one is suited to a different kind of practice. You can switch between them at any time in Settings.

Android: All deals on Android use Probabilistic Distribution, so every random deal is used. To filter out common hands and see hands you haven’t played yet, use the Win filter in Settings.
Default

Random Uniform Distribution

The app deals random tiles, then checks which hands those tiles match. If you've already practiced a matched hand recently, the app redeals and tries again — searching for tiles that fit a hand you haven't seen yet. Once most of the card has been covered, the cycle resets and starts over.

  • Best for learning the full card
  • Most hands get practice before any one repeats
  • The most-requested setting from players

See the comparison chart below for how this stacks up against Probabilistic Distribution.

Optional

Probabilistic Distribution

The app deals random tiles and uses every hand as it shows up. Hands that are easier to make naturally appear at the top of the suggested list more often, and harder hands less often.

  • Mirrors what you'll actually see at a real table.
  • Best for tournament-style and game-realistic practice.
  • Turn it on in Settings → Advanced → Probabilistic Distribution.

Side-by-side bar chart comparing how often each hand on the card was selected under Uniform Distribution versus Probabilistic Distribution. Uniform spreads selections evenly across most hands; Probabilistic concentrates selections on a smaller set of easier-to-make hands.
Two separate runs of 500 hands — one per mode. Uniform (left) spreads practice across the full card, while Probabilistic (right) simply uses every random deal as-is, so easier-to-make hands naturally show up more often. Ties for the highest-matching hand are counted in both totals.

Note: A few hands — like Quints 1 and W&D 1 and 2 — show near-zero counts in both columns. They’re still perfectly playable and winnable; they just rarely come up as the top-matching hand in a random 14-tile deal because of how the tiles are composed.

Which should I use?

Most players keep Random Uniform Distribution on while they're learning the year's card so every section gets the same amount of practice. Once you know the card well, switch to Probabilistic Distribution to train against the hand mix you'll actually see at a real table.
