A field guide to the simulator’s 17 named strategies.

Tries to play a useful number of tiles, shed meaningful points, preserve a flexible rack, and avoid making the table needlessly easy for the next player.

Try this at the table

Use this as your default mental checklist: Can I go out? What can I play? Which choice lowers my risk without wrecking my next turn?

Watch out for

A compromise can lose to a more decisive priority when the rack or score clearly calls for one.

Chooses the legal move that gets the most physical tiles off the rack; points break a tie.

Try this at the table

Count tiles before admiring patterns. A five-tile move usually deserves attention before a prettier two-tile move.

Watch out for

It can spend useful connectors or leave high-value tiles behind.

Chooses the legal move that removes the most rack points; tile count breaks a tie.

Try this at the table

When two moves are both sound, unload the 10s through 13s and any joker that could become a painful penalty.

Watch out for

Pure point shedding can break a more flexible low-number rack.

Emphasizes high-point tiles and favors less complicated table work, aiming to reduce the damage if another player ends the game.

Try this at the table

If an opponent is nearly out, stop saving an elegant rack and reduce the score you could be caught holding.

Watch out for

Playing too safely can pass up the fastest route to your own win.

Requires a stronger opening and may draw instead of making a marginal play, especially when the rack still has several ways to improve.

Try this at the table

Occasionally keep a genuinely versatile rack intact when the available play is small and opponents are not threatening.

Watch out for

Waiting feels strategic long after it has become expensive; this style performed poorly in the pilot.

Waits for a 45-point opening and is unusually willing to keep drawing rather than enter the table.

Try this at the table

Use this strategy to test the common temptation to wait for a spectacular opening. The pilot results do not support copying it in human play.

Watch out for

It can finish with a large, expensive rack; this was one of the pilot's clearest losing tendencies.

Aggressively sheds points and high tiles, and becomes comfortable spending jokers rather than holding them for a perfect moment.

Try this at the table

Switch into this mindset when a player has only a few tiles or when protecting a match lead matters more than building the ideal rack.

Watch out for

Used too early, it can spend flexible pieces before they have done their best work.

Plays normally in a single game, protects a large late-match lead by shedding points, and accepts more variance when far behind.

Try this at the table

With one game left, use the match score to decide whether to protect a lead or accept more risk in pursuit of a comeback.

Watch out for

The pilot did not establish reliable score-gap switching rules; its current thresholds are hypotheses to test.

Strongly prefers to keep a joker when another good legal play exists, preserving its flexibility for later.

Try this at the table

Do not spend a joker merely because you can; ask what concrete future problem it is solving.

Watch out for

A held joker is worth 30 penalty points, and the game can end before its flexibility pays off.

Values keeping jokers and places an especially high value on legally replacing and recovering one from the table.

Try this at the table

Scan every exposed joker for a replacement from your rack before evaluating ordinary plays.

Watch out for

Retrieving a joker is not automatically progress; the resulting move still needs to improve the whole rack.

Values tiles that connect to several possible runs or groups, while discounting duplicate copies that add little new potential.

Try this at the table

When choosing what to play, keep the tile that participates in several plausible future melds and release the more isolated copy.

Watch out for

Future flexibility is only valuable if you survive long enough to use it.

Prefers final table layouts with fewer obvious extension points for the next players.

Try this at the table

If two moves unload similar racks, prefer the table that exposes fewer easy ends and fewer reusable pivots.

Watch out for

Do not sacrifice substantial immediate progress for a small and uncertain inconvenience to opponents.

Opens at the legal 30-point threshold and mainly tries to place tiles, without valuing sophisticated rack shape.

Try this at the table

Its good habit is decisiveness: take clear legal progress instead of waiting for a masterpiece.

Watch out for

It can use flexible tiles carelessly because it does not think much about what remains.

Places a very large penalty on moving or rebuilding melds already on the table.

Try this at the table

Use it to model your current comfort level, then practice finding one more table-rearrangement option than feels natural.

Watch out for

This restriction left a great deal of playable value unused and produced the pilot's largest score penalty.

Uses visible rack counts and recent plays to become more reluctant to leave an easy table when an opponent appears close.

Try this at the table

Notice who is down to a few tiles and tighten up choices that would hand that player an obvious extension.

Watch out for

Public clues are incomplete; imagined opponent knowledge can overwhelm better immediate play.

Evaluates the exact mix of unseen tile types one draw ahead, rewarding racks with likely completions and penalizing tables that likely help opponents.

Try this at the table

After a close move, count how many unseen numbers can complete what remains rather than saying only that the rack 'looks flexible.'

Watch out for

One draw is still a short horizon and cannot forecast the full multiplayer game.

Selects randomly among legal candidates instead of expressing a coherent preference.

Try this at the table

Use it as a baseline opponent that shows whether a proposed strategy adds value beyond legality alone.

Watch out for

It is not intended as advice for human play.
