Ledger Lock
A timed arcade puzzle where you activate grid cells to match row and column target sums without letting two active cells touch edge to edge.
Ledger Lock is a fast, timed logic puzzle on the Play Trike site. Instead of one puzzle a day, it hands you a 90 second run and keeps loading fresh number grids for as long as you can keep solving them. On every board you switch on cells to hit exact row and column totals, and no two switched on cells may ever sit side by side.
What is Ledger Lock?
Each board in Ledger Lock is a 5x5 grid of numbered cells, and every row and column carries a target sum along its edge. Tapping a cell activates it, adding its value to both that row's total and that column's total. The catch is the adjacency rule, which the game states as: active cells cannot touch up, down, left, or right. Touching at a corner is fine, so diagonal patterns are always legal. Match every row and column to its target while respecting that spacing rule and the ledger is sealed, with the next puzzle loading instantly, all inside the same 90 second timer.
Unlike most games catalogued as dailies, Ledger Lock does not hand you one puzzle a day. There is no daily reset, no calendar of past boards, and no shareable daily result to post. What you get instead is an arcade style timer: press Start Shift whenever you want, seal as many ledgers as you can before the clock hits zero, and run it again immediately if you like. Some directories list it as a daily game, but that likely comes from the site itself, whose tagline promises a new casual web game every day. That refers to new games being added to the site, not to a daily puzzle inside this one.
Ledger Lock is published on Play Trike, a site run under the name FinePocket that hosts dozens of browser puzzle and arcade games with similarly styled two word names, including Updraft Skiff, Crest Stack, Lumen Counter, and Snare Grid. The games share a plain, no frills presentation: open the page, read the rules, and start playing without an account.
There is no win or lose screen in the traditional sense. You score 1 for every ledger you seal, your best seal count is saved locally on your device, and strong runs are eligible for a global TOP 20 leaderboard. A Clear button lets you reset a single board mid run if your taps go wrong. The overall feel is closer to a short, sharp arithmetic sprint than a slow daily brain teaser, useful for a quick break rather than a once a day ritual.
How to play Ledger Lock
- Open Ledger Lock at playtrike.com and press Start Shift to begin the 90 second timer.
- Look at the target sum shown for each row and column of the 5x5 grid.
- Tap cells to activate them; each active cell adds its value to both its row total and its column total.
- Never activate two cells that touch up, down, left, or right. Corner contact is allowed.
- If a board gets tangled, press Clear to reset that puzzle without ending the run.
- Seal the board by matching every row and column to its target, then keep solving the boards that load until time runs out.
Tips and strategy
- Scan for rows or columns with the smallest targets first, they narrow your options fastest.
- Plan cell placement diagonally when possible, since corner contact is always legal.
- Check both a cell's row and column target before tapping it, a cell that fixes one total can wreck the other.
- Use the Clear button early when a board goes wrong instead of untangling taps one by one, a fresh start on the same board is often faster.
- Don't chase a board you can't finish when the clock is near zero, only sealed ledgers score, so weigh your remaining seconds honestly.
- Play a few relaxed runs first to learn the typical range of target numbers before going for a personal best.
