Clearance Grid is an original browser simulator with free virtual coins and no cash redemption. Its mathematical checks apply to this demo only. They do not authenticate an outside company or demonstrate that any commercial game has the same rules.
Three rows, four columns and maximum selection
Twelve independent fair bits fill a board of three rows and four columns, in row-major order. One is occupied, zero empty. Sample the entire hidden board once, then reveal one cell automatically per step. The player does not choose cells or solve the selection.
Terminal raw reward is the maximum number of occupied cells selectable with no pair sharing a horizontal or vertical side. Diagonal neighbours are allowed. Empty cells cannot be selected. The engine finds an actual maximum automatically; a smaller valid selection does not establish the maximum. This is not the number of occupied cells or connected groups.
What Pakistani Players Should Check
When playing the 57BD clearance grid demo, remember that gambling is restricted by national law in Pakistan. This site is independent and not the operator. Always verify if the brand holds a valid licence by checking the operator's official website directly. Regarding payments, confirm if 57BD supports PKR (Pakistani rupee) and local methods like JazzCash or Easypaisa, as these are common in Pakistan. You must check this yourself with the operator, as this demo uses virtual coins. For safety, ensure you are an adult and play responsibly. Do not assume virtual wins translate to real cash. Always read the terms carefully before engaging with any real-money version of the game.
- Verify licence status on the operator's site.
- Check if JazzCash or Easypaisa are supported.
- Confirm PKR is the available currency.
Exact mean and revealed-information return
The initial mean reward is 3.8408203125 over all 4,096 equally likely boards. Quote = 0.97 × exact conditional expected terminal maximum / this initial mean. It includes every hidden suffix, not just the maximum of currently visible cells. It starts at 0.97× and may rise or fall.
Expected gross return is 97% for policies using only revealed information in this fair model, not a win probability, guaranteed balance or a reward for player selection skill. Zero ends immediately. Only the empty complete board has terminal reward zero; a positive final quote settles automatically. Gross return includes returned stake, without another 3% factor.
Full board, diagonal cells and exact frequencies
An empty board rewards zero. A full three-by-four board rewards six: either checkerboard colour gives six nonadjacent cells. The grid can be partitioned into six disjoint neighbouring pairs, so a selection can contain at most six. Two occupied diagonal neighbours may both be selected; two occupied side neighbours allow at most one.
Across all 4,096 boards, maxima 0 through 6 occur 1, 29, 281, 1,105, 1,701, 852 and 127 times. A new occupied cell cannot lower the visible maximum, but the conditional quote may fall when a newly revealed cell is empty. Visible cells alone do not give the complete-board expectation.
Collection and unreachable high Auto thresholds
Before starting choose stake 10, 20, 50 or 100 and Manual or Auto threshold 1.2×, 1.5×, 2×, 3× or 5×. One stake and these settings are captured. Settings and refill lock while active. Auto is a collection threshold, not repeated play. Reduced motion changes timing only.
Manual Collect first processes reveals due at the current timestamp. An earlier Auto crossing pays its full actual quote before later events. Zero before a crossing loses. The largest possible quote is about 1.515301×: Auto2×,3× and5× cannot trigger. These still wait for automatic final positive settlement rather than lose solely because the threshold was not reached.
Manual refill below ten coins
A new local wallet starts at 1,000 free coins. The balance and fractional payout carry are stored in this browser’s localStorage. Whole coins are credited from each payout while its fractional remainder carries forward. They have no cash value.
Refill is manual and available only while idle with a balance below 10. It sets the balance to 1,000 rather than adding 1,000, and preserves fractional carry. It is neither a timed refill nor a reset available during a round. No promo code or deposit is involved.
Frequently asked questions
Does the name establish an operator?
57BD is a search reference in this independent guide. It does not establish a verified publisher, official domain, licence, app, support channel or payment service. The guide does not authenticate an outside operator or conclude that absence from an unspecified list proves fraud.

Do I choose the maximum cells?
Twelve independent fair bits fill a board of three rows and four columns, in row-major order. One is occupied, zero empty. Sample the entire hidden board once, then reveal one cell automatically per step. The player does not choose cells or solve the selection. Terminal raw reward is the maximum number of occupied cells selectable with no pair sharing a horizontal or vertical side. Diagonal neighbours are allowed. Empty cells cannot be selected.
