NV casino

NV casino is a compact, one-thumb number puzzle in the Survo style. Fill the grid with the numbers 1 to N, each used exactly once, so that every row total and every column total matches the value shown beside it

A few numbers start locked in. From those and the row and column sums you can reason your way to the rest — pick a number, tap a cell, and any wrong total lights up right away

All 20 levels are generated to be solvable by logic and to have exactly one answer, so progress always feels earned rather than lucky.

NV casino plays fully offline. No accounts, no network, no forced ads, nothing to buy.

- Survo-style sum logic across 20 rising levels
- Row and column sums pin a unique answer
- Instant wrong-sum highlighting
- One-thumb play: pick a number, tap a cell
