Bots

The three difficulties, whether they call last card, and the avatars they wear.

Empty seats can be filled by bots, so a table is playable with one human.

The three difficulties

Bot = {
    Difficulties = {
        Easy   = { randomness = 0.5,  callsLast = false },
        Medium = { randomness = 0.15, callsLast = true },
        Hard   = { randomness = 0,    callsLast = true },
    },
    DefaultDifficulty = "Medium",
},

Field	What it does
`randomness`	Chance from 0 to 1 of playing a random legal card instead of the best one
`callsLast`	Whether it calls last card in time

randomness is the whole difficulty model, and it works well for this game because the best play is usually obvious: dump the expensive card, keep the colour you have most of, save the wild. A bot that does that half the time is a beatable opponent rather than a weak one.

Hard at zero randomness always plays its best card. It is not unbeatable: this is a game with a shuffled deck and hidden hands, so a good player loses to a bad one regularly.

callsLast is the difficulty that players notice

An Easy bot forgets to call its last card and takes the two-card penalty, which is exactly the mistake a distracted human makes. It is the single most human thing in the setting.

Turning it on for Easy makes the difficulty gap much narrower, because the endgame is where games are decided.

Timing

Timing = {
    BotMoveDelay = 0.9,
    BotLoadMinSeconds = 0.5,
    BotLoadMaxSeconds = 8,
},

Field	Default	What it does
`BotMoveDelay`	`0.9`	Pause before a bot plays
`BotLoadMinSeconds`	`0.5`	Minimum time the loading splash stays up
`BotLoadMaxSeconds`	`8`	Longest wait for a bot avatar before starting anyway

Nearly a second per bot move is deliberate. With three bots and no delay, a human's turn comes back before they have seen what happened.

Avatars

UseFriendAvatar = true,
FallbackUsernames = { "builderman", "Shedletsky", … },

With UseFriendAvatar = true a bot borrows the appearance of a random friend of the player. Failing that it uses one of twelve fallback usernames.

The shipped fallbacks are well-known Roblox accounts. They are recognisable, which reads as a wink rather than as filler, and none of them belong to you.

Consider replacing the fallback usernames

Twelve famous accounts sitting at your card table is a fine default and a slightly odd look for a serious game. If your experience has its own characters, put their usernames here instead.

The list is used in order of availability, so it needs several entries to fill a four-seat table with distinct opponents.

Do bot games count

Leaderstats = {
    CountBotGames = true,
},

On by default: wins and losses against bots count. There is no separate switch for points.

That is more generous than the equivalent settings elsewhere in the range, and it is worth reviewing if you run public boards. A player can sit alone at a table with three Easy bots and win most of them.

Setting CountBotGames = false records nothing from bot games, which makes bot play pure practice.
