==================================================
NEW - Version 3 (v3.11.1): completely renewed

==================================================

The previous description was out of date, so this page has been rewritten for
the new version. Version 3 is a full rework of the game:

• The lottery is decided at lever-on, just like a real pachislot.
• Six settings plus an event setting "S", with a tuned RTP curve
  (setting 1 89.9% ... setting 6 130.1%).
• A Chance Zone battle, set-based AT whose continuation is the base level,
  BASE DEFENSE, AIRDROP RUSH, a ceiling and a CZ through ceiling.
• Real-machine presentation: three screens, step-ups, notice lamp, big
  animated titles and a Million God style freeze.
• Hand out settings to a whole row of machines in one command
  (collect / normal / release).
• Bet multiplier up to x20 (admins only).
• English and Japanese.

Upgrading from 1.x / 2.x: use the bundled configs/SlotMachineJP.json and
data/SlotMachineJP_Tables.json, and delete carbon/lang/*/SlotMachineJP.json
once. Machines you already placed keep working (from 1.x, set their settings
again).

SlotMachineJP - Japanese Pachislot for Rust

==================================================

SlotMachineJP turns Rust's slot machine into a full Japanese "pachislot"
(AT type). Using Harmony patches, it replaces the spin lottery and the payouts
with a complete game cycle: a hidden mode, forewarnings, a Chance Zone battle,
a set-based AT with a base-defense continuation battle, an add-on zone, a
ceiling and a premium freeze - all wrapped in a Rust survival story.

If your players are bored of the plain Rust slot machine, this brings the real
tension and rhythm of a Japanese slot hall to your server.

The Game Cycle

The lottery is decided the moment the lever is pulled; the screen reveals it
while the reels spin. Players never know exactly where they are - that
uncertainty is the whole point.

• Normal (SURVIVE)
  Small roles (replay, bell, cherry, watermelon, rare) are drawn every spin.
  Cherry and watermelon roll for the Chance Zone with odds set by a hidden mode;
  a rare role can enter the Chance Zone or even go straight to AT, and three
  sevens give a direct AT.

• Forewarning
  "Something is coming..." - a few games of rising tension before a Chance Zone
  or AT. Some forewarnings are fake.

• Chance Zone - MONUMENT RAID (5-30 games)
  A battle. The enemy you face shows how likely you are to win:
  Bradley < Heavy Scientist < Polar Bear < Chicken (premium). Cherry and
  watermelon raise the chance or win outright; a rare role or sevens win at
  once. Your weapon (bow -> pistol -> AK -> rocket launcher) climbs as an
  expectation display. Many wins are drawn out to the final game.

• AT - RUST RUSH (40-game sets)
  Sevens line up at a high rate. Your base level (Lv1 twig ... Lv5 armored)
  is the continuation rate (20% ... 85%) and rises on rare roles. Sub roles add
  extra games.

• BASE DEFENSE (5 games)
  At the end of each set the raiders attack wave after wave while the base's
  durability drops. Defended - next set; base fell - the AT ends. A rare role
  can still rewrite a loss into a continue.

• AIRDROP RUSH (3 games)
  Entered from watermelon / rare roles during AT. Every game is an add-on; the
  total decides the LOOT RANK (C ... SS).

• Freeze (1/8192)
  Blackout, lightning, "GOD" lines up one reel at a time - a 200-game AT with a
  strong base guaranteed.

Spec of the bundled tables (simulated, 1 billion spins per setting)

Ceiling 250 games (CZ guaranteed), CZ through ceiling 5 (the 6th CZ wins).
Every number is in the tables file and fully editable.

Key Features

• SIX SETTINGS + EVENT SETTING "S"
  Settings 1-6 like a real machine, plus "S" for events (CZ about every 32
  games, short 20-game sets). Set one machine with /slotjp setting.

• SET A WHOLE ROW AT ONCE
  /slotjp area hands out settings to the machines around you so their average
  hits a target - collect (95%), normal (110%) or release (114%) - with a small
  or large spread, and resets them for the next day. Different every time, and
  machines in use are left alone. Also from RCON.

• HIDDEN MODE SYSTEM (Low / Normal / High / SuperHigh)
  Each machine drifts between four modes that decide how easily it enters the
  Chance Zone. Mode hint screens tease the player without revealing the truth.

• CEILINGS
  A guaranteed Chance Zone after 250 games without a hit, and a guaranteed win
  after 5 Chance Zone misses in a row.

• REAL-MACHINE PRESENTATION
  Three screens (main LCD for the show, a progress panel, a data bar),
  expectation-coloured step-ups (white ... rainbow), a "RUSH" notice lamp
  (before or after the reels), frame and stop-button lamps, sounds, big
  animated titles, AT-confirmed patterns and the freeze cinematic. Pulling the
  lever cuts the previous effect, so fast play always stays in sync.

• DATA COUNTER + NET GRAPH
  Like a real slot hall, every machine keeps spins, in/out, net, RTP, current
  dry spell, ceiling counter and bonus history, saved across restarts. Players
  open the data panel and the net graph from the machine's screen.

• BET MULTIPLIER UP TO x20
  One spin bets 3 scrap x the multiplier and pays out the same multiple. Only
  admins can change it (in game with the machine's buttons, or by command) -
  not even the machine's owner.

• ENGLISH AND JAPANESE
  All texts are in language files, so you can edit them.

• FULLY DATA-DRIVEN
  Plugin settings (SlotMachineJP.json) and every gameplay number
  (SlotMachineJP_Tables.json) live in JSON files and hot-reload in game. The
  bundled tables were tuned with a simulator of the plugin's own lottery.

• ADMIN & TEST TOOLKIT
  Place, convert, configure, inspect and reset machines, plus test commands to
  force states, modes, the ceiling, forewarnings, a CZ, the base level, the
  freeze and to preview every effect.

Symbols & Payouts

Reel faces are Rust items. Three of a kind pays (defaults):

Charcoal 3, Wood 3, Rope 4, Bandage 5, Low Grade Fuel 6,
Sulfur Ore 7, Scrap 10, Lucky Seven 15

A single Low Grade Fuel (cherry) pays 1. All payouts are multiplied by the bet
multiplier and are configurable.
