Grail Break Expansion Plan

Once $BREAK has migrated and trades freely, Grail Break adds three features: Spin Upgrade, then Graildex, then Battle Slabs. The order runs from closest-to-built and lowest-risk to newest and riskiest.

01Spin Upgrade

Risk-free surprise upgrades. A Spin Fund in ops very rarely bumps a solo pull one machine up, free.

02Graildex

Scan any graded card, see its price history and a plain Hold or Sell call. Free data only.

03Battle Slabs

2 to 8 players rip the same machine. Best slab takes every slab; close calls split the pot.

Drafted 16 Oct 2026

Where we start

Most of what these features need is already live. The new work is mainly game logic and screens on top.

Already live	What it gives the new features
Collector Crypt machines ($25 · $50 · $100 · $250 · $500)	The packs every upgrade and battle rips from
Commit-reveal oracle (/fair)	Provably fair upgrade rolls and battle results
Ops page, treasury wallets, sweep	Where the Spin Fund is switched on and topped up
Collection with 72h sell-back and ship-to-me	Where won slabs land and how players cash out
Recent CC pulls + our own hits data	The first price history Graildex can show
Go Live	Battles hosted on stream
Earned Pro and breaker levels	Gates and perks for each feature

Feature 01

Spin Upgrade

A surprise, not a purchase. When it's switched on, a Spin Fund that ops fills pays for very rare free upgrades. A player ripping a solo gacha pull is, once in a long while, bumped one machine up. They never pay extra and can't lose anything.

Example. Ops puts $1,000 in the Spin Fund. A player rips a $25 solo pull. The oracle roll hits, the fund pays the $25 difference, and the player rips a $50 pack instead. That $1,000 covers 40 of those surprise upgrades.

Ops controls

On / off

One switch. Off = no upgrades, fund untouched.

Spin Fund

Balance and top-up from a treasury wallet. Empty fund turns it off by itself.

How rare

Chance per solo pull. placeholder: 1 in 500

Daily cap

Most upgrades or dollars per day, so one lucky streak can't drain it.

What one upgrade costs the fund

Pull	Upgraded to	Fund pays
$25	$50	$25
$50	$100	$50
$100	$250	$150
$250	$500	$250

What gets built

Spin Fund wallet + switch, rarity and daily cap on the ops page, with undo.
An oracle roll on every solo pull while it's on; each roll is checkable on /fair.
On a hit, the fund pays the gap and the real Collector Crypt open uses the next machine up.
Reveal: an "UPGRADED" moment before the normal rip, and a post in the HQ feed.

Feature 02

Graildex

Scan a graded card, get its price history and a Hold or Sell call based on data. Works on any card, not only ones pulled on Grail Break, so it brings in collectors who have never ripped with us.

Example. A player scans a PSA 10 they pulled. It sold for $180 three months ago and $140 last week, with fewer sales each month. Our sell-back offer is $150. The call reads Sell: the offer beats the latest sales and the price is falling.

What a scan shows

Card, set, grader and grade, from the cert number or a photo of the slab
12-month price chart, each sale a point
How often it sells, and how far prices swing
Current sell-back offer next to the market price
The call: Hold, Sell or Watch, with its two or three reasons

How the call is made

Sell — sell-back offer at or above recent sales, or price falling 60+ days on steady volume.
Hold — price rising on steady or growing volume, offer below market.
Watch — too few sales to judge.

Data — all free

v1: our own pull history plus Collector Crypt's recent pulls and values (already collected).
v2: eBay sold listings and other free sources, for cards beyond Collector Crypt. No paid feed.

Every call says it reads past prices and is not financial advice. Free scans with a daily limit; Pro and $BREAK holders over the threshold get unlimited scans and price alerts.

Feature 03

Battle Slabs

Head-to-head rips. Every player rips one pack from the same machine at the same moment; the most valuable slab wins every slab in the battle.

Example. Four players each pay $50 plus the 3.5% fee and rip a $50 pack at once. One pulls a $140 slab; the others pull $30, $35 and $45. The $140 puller takes all four slabs, $250 of cards.

How a battle runs

A player opens a battle: machine and size (1v1, 4-way or 8-way).
Others join by paying the seat. It starts when full; unfilled battles refund after a set time.
The oracle commits a seed before anyone joins and reveals it at the rip (checkable on /fair).
All packs open live, lowest to highest.
The winner keeps, sells back within 72h, or ships.

Ties

Close counts as a tie. Top slabs within a small band of each other are tied. placeholder: within 5%
Grade breaks it first. Higher grade wins the whole pot.
Same grade = split the pot. The oldest card gets the bigger share. placeholder: 60 / 40

Tie example. Same four-way battle, but the pulls are a 1999 PSA 10 at $140, a 2023 PSA 10 at $136, then $34 and $40. The top two are within 5% and the same grade, so it's a tie. The pot is $350 of slabs. The 1999 card's owner gets 60% ($210), the 2023 card's owner 40% ($140), settled in slabs first and the remainder in USDC.

Rules to lock down

Value = Collector Crypt's listed value at the moment of the rip, frozen on screen.
Who can open one — anyone for $25 and $50; Pro for $100 and up.
Live — battles plug into Go Live so breakers can host them on stream.

Rollout

About six weeks from migration to all three live. Diamonds are gates: the next step opens only when the gate is met.

Risks

Battle Slabs looks like gambling. Paid entry with winner-take-all is the closest thing to a wager we'd run. Needs a legal read and maybe region limits.
Spin Fund drains fast. Rarity set too loose empties it in a day. The daily cap and the auto-off when empty stop that.
Graildex calls a card wrong. A bad Sell on a card that then climbs costs trust. It shows its reasons and says Watch when data is thin.
Free data breaks. eBay and other free sources can change or block scraping. v1 runs on our own data, so Graildex never goes dark.
Collector Crypt dependence. Upgrades and battles rip from CC. If their API changes, both pause.
