Today's card shows the rack with its cages, targets and given cells only, your time band, streak and the days to launch; a card for an earlier day shows that day's numbers. Never today's answer.

Fill the rack with 1 to N, no repeats in a row or column, so that every cage reaches its target with its operation. 6×6 on weekdays, the 7×7 full rack at the weekend, a 4×4 warm-up, an on-page number pad, pencil marks, live rule checks, one hint, a streak, personal bests and a spoiler-free result to share. A fan puzzle about an imagined server rack, never a status signal.

How to play

The rack is a grid cut into outlined cages. Fill it with 1 to N so that no number repeats in a row or column and every cage reaches the target in its corner with its operation (+ add, × multiply, − the difference of two cells, ÷ one cell divided by the other; a one-cell cage is given). Tap a cell, then a number on the pad; switch to pencil to jot candidates. A repeated number turns red, a full cage's target turns green when met and red when missed, and the checks only ever look at the rules, never at the answer. Undo and Clear all are there when a cage goes wrong. Every rack is checked when the site is built by a solver that prunes candidates under the same rules you use (the numbers left for a row and column, the sets that reach each cage) and then tries the rest, so each has exactly one answer and opens with a cage that gives something away at once; the 4×4 warm-ups fall to the named rules alone, with no guessing at all.

Tip one: a two-cell cage marked 1− holds neighbours. Its two numbers differ by one, so they are a pair like 3 and 4 or 5 and 6, and whichever other numbers already sit in that row or column rule pairs out fast; a 1÷ cage never exists (nothing divides to 1 except a repeat), while a 2÷ cage on a 6×6 is one of 1 and 2, 2 and 4 or 3 and 6. Tip two: a three-cell 6× cage in one straight line is 1, 2 and 3. Three different numbers that multiply to 6 can only be those, and since they share a row (or column) the rest of that line is 4, 5 and 6 (and 7 at the weekend). Then let the lines do the work: a row with one cell open takes the one number missing, and a number with only one place left in a row or column goes there.

Everyone gets the same rack on the same UTC day: 6×6 on weekdays, the 7×7 full rack at the weekend, and newcomers can switch on the 4×4 warm-up, which still counts. One hint a day fills one cell the rules force, says which rule, and marks the result as assisted. When the last cage turns green the rack's status lights go green one by one and the rack lead signs off with your time; Give up shows the answer and ends the day without a balance. The archive lets you play any earlier day's rack and practice racks come from a spare pool; both are marked and never count. Load Balancer is a fan puzzle about an imagined server rack: nothing here is a server, a status figure or an asset from GTA 6, the cages are abstract shapes and never a logo, nothing comes from a leak, and nothing is presented as official. For more deduction try the Coolant, the Cold Start and the Load Order.

Questions

What are the rules?

Fill the rack with the numbers 1 to N (6 on a weekday rack, 7 on the weekend full rack, 4 on the warm-up) so that no number repeats in any row or column. The grid is cut into outlined cages; each cage shows a target and an operation in its top-left cell, and the numbers in the cage must reach that target with it: + means they add up to it, × means they multiply to it, − means the difference of the two cells, ÷ means one divides the other to give it. A cage of one cell is simply that number. A number may repeat inside a cage as long as it never shares a row or column. Every rack here has exactly one answer.

How do I enter a number?

Tap a cell, then tap a number on the pad under or beside the rack; no phone keyboard ever opens. Tap ✎ pencil to switch to pencil marks: numbers then toggle small candidate notes in the cell instead, and placing a number later sweeps that mark from its row and column. ⌫ clears the cell. On a keyboard the arrows move, 1 to 7 enter, 0 or Backspace clear, P toggles pencil, U undoes, Enter checks, Escape drops the focus. Undo takes back the last change; Clear all empties the rack but keeps the given cells.

What do the highlights mean?

A number turns red when it already sits in the same row or column. A cage's target turns green once every cell of the cage is filled and the numbers reach it, and red when the cage is full and they do not. The checks only ever look at the rules, never at the answer. One hint a day fills one cell the named rules force, says which rule in words, and marks the result as assisted. Give up shows the answer and ends the day without a balance.

What is the warm-up?

A 4×4 rack for newcomers, switched on with the Warm-up toggle (remembered on this device). Every warm-up falls to the named rules alone, with no guessing. It counts as the day's solve; the 6×6 weekday and 7×7 weekend racks are what the best times are about.

Is this a real status signal?

No. Load Balancer is a fan logic puzzle about an imagined server rack in an imagined status room. Nothing here is a server, a load figure, a queue or an asset from the game or its services, the cages are abstract shapes and never a logo, nothing comes from a leak, and nothing is presented as official. For the real launch-day status picture, see the status page and the readiness guides on this site.
