Rules & FAQ
Read this before you play. Especially if it's your first crypto-tipgame.
⚠ Disclaimer — read first
• If you don't know what you're doing — don't do it.
• Never send funds you can't afford to lose.
• Smart contracts and wallets can have bugs. Networks can be congested. Transactions can fail.
• Prize-pool distribution depends on on-chain conditions (gas, slippage, network availability). Payout timing is a target, not a promise.
• You are responsible for your own taxes wherever you live.
• If gambling is restricted in your jurisdiction or you are under the local legal age — do not participate.
By creating an account, sending donations or claiming payouts you accept these terms. If you don't agree — close this page and don't take part. The dev team reserves the right to fix bugs, correct match results, and adjust scoring rules transparently if data sources disagree.
1. Register
Create an account with a username + email + password. Pick a country (you'll get a BOBAI in that national jersey as your avatar once the illustrator delivers). Email is used only for confirmation + password reset — never shown publicly, never spammed.
Before the account is created you'll see a short security briefing (anti-scam, anti-phishing, game disclaimer) that you have to acknowledge. After confirming, a confirmation link is sent to your inbox — click it once and you're in.
Optionally link a BEP-20 wallet (MetaMask, Trust Wallet, Binance Web3, hardware — any wallet works). You just paste the address — no signing, no app install, no gas. The wallet is only needed if you want to be eligible for prize-pool payouts. You can play purely for fun without one — your username will still appear on the leaderboard, just without the ⚽ icon.
2. Bonus questions (one-time)
Five long-shot predictions, each worth 10 points. Lockable at the first match's kickoff:
- Who wins the World Cup? (single team)
- Team with the most goals scored across the tournament
- Team with the fewest goals scored
- Top scorer's country (Golden Boot)
- Total red cards bracket: <5 / 5–9 / 10–14 / 15–19 / >19
You can edit your answers any time before the first kickoff. After kickoff: locked — no changes.
3. Match tips
For every match you tip the exact score (e.g. 2:1). All 72 group-stage matches plus 32 knockout matches.
Each match locks 15 minutes before kickoff. After that: no edits possible (enforced at database level — you literally can't get around it).
Knockout matches start as TBD vs TBD in the UI and become tippable once the draw resolves them.
4. Crypto predictions
Predict the USD price of BTC, BNB and BOBAI at the exact moment of the World Cup Final kickoff (19 July 2026, 19:00 UTC). Live current prices are shown for reference; you can edit anytime until the opening-match kickoff (11 June 2026, 19:00 UTC) — that's the submission deadline.
Scoring is based on absolute difference to the actual price at the snapshot moment — the closest guess on each coin wins that coin's share of the crypto pot.
5. Scoring
Match scoring (per match)
Raw points stack — first you get points for calling the winner (1/X/2), then a bonus on top if you also got the goal difference, and another bonus on top if you nailed the exact score:
| Outcome | Example (tipped 2:1) | Raw points |
|---|---|---|
| Correct winner only (1 / X / 2) | Actual 4:0 — right side, wrong margin | 2 |
| Correct winner + correct goal difference | Actual 3:2 — right side, 1-goal margin matches (+1) | 3 |
| Correct winner + GD + exact result | Actual 2:1 — nailed it (+2) | 5 |
| Wrong winner / wrong direction | Actual 0:1 or 1:1 | 0 |
A correct draw tip (X) only counts if the actual result is also a draw — the score doesn't have to match exactly to get the 2 base points, but you need an actual draw for the +1 GD bonus and an exact draw score for the +2 exact bonus.
Phase multiplier
Knockout matches matter more. Raw points get multiplied by the phase — the deeper the tournament, the bigger the swing on the leaderboard:
| Phase | Multiplier |
|---|---|
| Group stage | ×1 |
| Round of 32 | ×2 |
| Round of 16 | ×3 |
| Quarter-finals | ×4 |
| Semi-finals | ×5 |
| Third-place match | ×6 |
| Final | ×7 |
A perfect exact-score tip in the Final is worth 5 × 7 = 35 points — enough to flip the leaderboard on a single match, which is exactly the point.
Bonus & Crypto
Bonus questions: 10 pts each if correct. Crypto: not counted in points — winners are determined by closest absolute price difference (own pot).
Tie-breaker
If two players have the exact same point total in a payout group, the player with more BOBAI in their linked wallet at payout time wins. Players without a linked wallet automatically rank below players with one in case of a tie.
6. Prize pool
Where the BOBAI comes from
Two sources feed the prize-pool wallet (0x5E41…D105):
- Token tax auto-flow: from 11 Jun 2026, 00:01 UTC until the Final (19 Jul 2026, 23:59 UTC), 0.52 % of every BOBAI buy/sell tax flows into the prize-pool wallet automatically — 0.26 % redirected from the BOB-burn slice + 0.26 % from the creator slice. The 3 % on-chain tax rate stays fixed; only the off-chain distribution changes for the WC26 window. After the Final, the split reverts to the standard 1 % BOBAI burn · 1 % BOB burn · 1 % creator.
- Donations: anyone can send BNB or USDT (BEP-20) to the prize-pool wallet. Incoming funds are auto-swapped to BOBAI via PancakeSwap and added on-chain. Any amount welcome — see below.
Everything is verifiable on BscScan. The pool figure displayed on the leaderboard reads the actual on-chain BOBAI balance — there's nothing in a back-office database we could fudge.
Pool split
How each incoming BOBAI gets allocated depends on the tournament phase at the moment it arrives:
- During group-stage matches: 60 % → Group Pot · 30 % → End Pool · 10 % → Crypto Pot
- From R32 onwards: 90 % → End Pool · 10 % → Crypto Pot (Group Pot stops growing — it's paid out before KO starts)
7. Payouts
Group Pot (60 % of group-stage collection)
Paid one day after the last group-stage match. Split across 32 winners from three sub-brackets:
| Sub-bracket | Who qualifies | Share of group pot |
|---|---|---|
| Group 1st | 1st-placed player in each of the 12 groups | 55 % |
| Group 2nd | 2nd-placed player in each of the 12 groups | 30 % |
| Best 3rds | 8 best 3rd-placed players across all groups | 15 % |
Within each sub-bracket, the share is split equally among its members — every group 1st gets the same slice of the 55 %, every group 2nd gets the same slice of the 30 %, and every best-3rd gets the same slice of the 15 %. The bracket weights still guarantee that being 1st always pays more than being 2nd, and being 2nd always pays more than just sneaking into best-3rd.
| Position | Share per player |
|---|---|
| Group 1st (×12) | 55 % ÷ 12 ≈ 4.58 % of group pot each |
| Group 2nd (×12) | 30 % ÷ 12 ≈ 2.50 % of group pot each |
| Best 3rd (×8) | 15 % ÷ 8 ≈ 1.88 % of group pot each |
Flat split inside the bracket = no “winner-take-most” effect; finishing 1st of your group with 30 group_points pays the same as finishing 1st with 60. The only thing that matters is which position you finished.
End Pool (KO-phase pot)
Paid one day after the Final. Top 4 overall — based on total score across all phases including bonus questions. Within the top 4 the split is tiered by position:
| Overall finish | Share of end pool |
|---|---|
| 🥇 1st | 50 % |
| 🥈 2nd | 25 % |
| 🥉 3rd | 15 % |
| 4th | 10 % |
Fixed percentages — climbing one position is always worth a meaningful jump. Bonus questions count in the total points that determine your rank, so don't skip them.
Crypto Pot (10 %)
Paid one day after the Final, alongside the End Pool. Split into 3 equal slots:
- 3.3 % of total pool to the closest BTC guess
- 3.3 % of total pool to the closest BNB guess
- 3.3 % of total pool to the closest BOBAI guess
The same player can win multiple Crypto Pot slots if they have the best guess on more than one coin.
Eligibility
Holder-balance cap: max 26× your BOBAI
Each individual payout to a winner is capped at 26× the BOBAI balance held in their linked wallet at the moment of payout. Examples:
| Your wallet holds | Maximum single payout |
|---|---|
| $1 in BOBAI | $26 |
| $10 in BOBAI | $260 |
| $100 in BOBAI | $2,600 |
| $1,000 in BOBAI | $26,000 |
| $10,000 in BOBAI | $260,000 |
Don't worry about being "capped out". Nobody knows in advance how big the prize pool will be — but if the pool grows, your BOBAI balance grows with it (same token, same chart). So the cap scales with you. Holding more BOBAI literally raises your ceiling.
The balance is read live from the blockchain at payout time — there's no snapshot to game and no way to fake it.
Cap overflow — cascading redistribution
If a winner's computed share exceeds their personal 26× cap, the excess does not stay with that winner and is not kept by the team. It flows to the rest of the eligible winners in the same pot. Each pot (Group, End Pool, and the three Crypto pots) is evaluated independently — overflow never crosses pot boundaries.
- Compute every winner's raw share based on points / closest-guess logic.
- Apply each winner's 26× cap. Sum up the overflow from anyone who got capped.
- Redistribute that overflow proportionally to the remaining (uncapped) winners within the same pot.
- If that redistribution pushes a new winner over their cap, repeat step 2 — the cascade continues until either every dollar is paid out within someone's cap, or no eligible uncapped winner remains.
- If after the full cascade residual still remains (every winner in that pot is capped out), the leftover BOBAI is added as permanent liquidity to the BOBAI/BNB PancakeSwap pool, and the resulting LP tokens are burned to the dead address. It is never carried into another pot, never refunded, never kept by the team — the value flows back to every BOBAI holder through a deeper, tighter market.
The cascading logic is implemented in the same payout-computation code that the admin runs before signing. The full split (raw share, cap applied, redistribution rounds) will be published on-chain alongside each payout batch so anyone can verify it.
How the payouts run
Payout transactions are triggered manually by the project admin (not fully autonomous) — the code computes the exact split (including cap and cascade), then the admin signs and broadcasts the batch. This is a deliberate safety design: an off-by-one bug should never auto-drain the pool.
8. Donations
The prize-pool wallet accepts BNB and USDT (BEP-20) on BNB Smart Chain. Address is shown on the Leaderboard page with a copy button.
How it works:
- You send X BNB or USDT to the prize wallet
- The pool sync worker detects the new balance
- BNB/USDT is auto-swapped to BOBAI via PancakeSwap
- The new BOBAI is added to the pool (verifiable on BscScan)
- Pool display updates within ~5 minutes
Any amount welcome. For gas efficiency we suggest at least the equivalent of ~$5, but anything works.
9. Security & manipulation safety
- Tip lock: 15 minutes before kickoff, enforced at the database level — not just in the UI.
- Bonus & crypto lock: enforced at the database level when the relevant match kicks off.
- Match results: only the sync worker (using a service-role key, never exposed to users) can write results. Players cannot edit goals.
- Scoring: runs in a database trigger after match results are written. The trigger overwrites any user-side `points` value, so nobody can self-award points.
- Wallet linking: you just paste your BEP-20 address — no signing, no seed phrase, no private key. We never ask for any of that, and the app would never need it.
- Wallet privacy: your linked wallet is never shown to other players in-app. The only public reveal is the on-chain payout transaction itself — and Group-Pot payouts are sent in randomized order across the 12 groups (e.g. group F may receive before group A), so observers cannot match a wallet to a specific group placement. Only the End-Pool top 4 (🥇/🥈/🥉/4th overall) and the three closest crypto guesses (BTC/BNB/BOBAI) are matchable to a wallet, because those are unique single-winner positions that are already public on the leaderboard.
- Tie-breaker by BOBAI balance: read live from the blockchain at payout time, not from a database — un-fakeable.
- Payouts: manually triggered by admin, not autonomous. An admin error or bug can be caught before signing.
- Prize wallet: a fresh dedicated wallet. Private key is only stored in encrypted Cloudflare Worker secrets — never in code, never on a server you can SSH into.
