No download is required
This guide supplies a browser-based demo, without a downloadable app or APK. It has not verified an official outside l77 app or store listing. Installation is not needed to use this site’s own demo. Browser-based game calculations and local wallet state do not mean the delivered page makes no external network requests.
The constrained hazard sets
The board has 4 × 4 cells labelled 1–16 in row order. Choose 3, 4 or 5 hazards before starting. The game samples uniformly from complete hazard sets whose label product and label sum have the same remainder modulo 7. There are 72, 309 or 636 eligible sets, respectively. This is not an independently uniform hazard grid: the printed labels define the constraint, rather than revealing the hidden set.
Stake, hazard count and locked controls
Select a stake of 10, 20, 50 or 100 play coins; the default is 20. The default hazard count is 3. Stake, hazard count, refill and starting another round are locked while the current round is active. Starting captures one stake for the whole board. During the round you can make eligible reveals and, after a safe reveal, collect.
Collecting, the cap and automatic banking
You may collect only after at least one safe reveal. Each cell is disabled if its possible safe-result gross value would be greater than 1000 times the captured stake; equality is allowed. The game banks automatically only when no eligible uncertain choice remains. The cap alone is not a rule that every capped state auto-collects. Eligible certainly safe cells do not increase the quoted value.
Reloading and browser data
Reloading before settlement leaves the already captured stake deducted and ends the unfinished round without refund, payout, continuation or resume. The stored wallet remains, but the round does not. Controls reset to stake 20 and 3 hazards. Clearing cached resource files alone may leave localStorage intact; clearing this site’s data can remove the saved wallet and carry.
Local storage, fonts and counter
The wallet balance and fractional carry are stored in browser localStorage. The delivered page requests Google Fonts resources, and the builder adds the Statinside 44 visit counter. Account-free play does not establish that no personal data are processed. Server access logs may exist; their contents and retention have not been established by this guide. These observations do not establish anonymity, a no-sharing policy or an infrastructure-wide privacy guarantee.
Frequently asked questions
Does this guide supply an APK?
No. It supplies a browser demo and has not verified an official outside app.
Is all round progress saved?
No. The wallet persists while storage is retained; an unfinished round cannot resume.
Are hazard sets random?
Yes: the complete eligible sets are sampled uniformly. They are constrained by the product/sum modulo-7 rule.
