MinesweeperClear every safe square. Right-click or press F to flag a mine. Arrow keys move; Enter reveals. Click a revealed number to clear its neighbors when enough flags surround it. Your first square is always safe.
SolitaireBuild the four foundations from Ace to King in one suit. Stack descending cards in alternating colors below; only a King can fill an empty column. Drag a card or a run, or click a card then its destination. Double-click a card to send it to a foundation. Click the deck to draw; click its empty space to recycle. Enter or Space selects cards; arrow keys move between piles. Escape cancels a selection. Game lets you deal again or choose draw one/three.
CalculatorEnter an address and prefix, then press =.
Enter an IPv4 address with a prefix, such as 192.168.1.10/24, or a dotted mask: 192.168.1.10 255.255.255.0. A bare address uses /32.
Enter calculates, Escape clears. /24 and /32 replace the prefix. Copy copies the complete subnet report. All calculations stay in your browser.
/31 allows two point-to-point endpoints; /32 describes one address. Counts do not determine whether an address is routable or available.
Operations run in order: 2 + 3 × 4 = 20. Press = again to repeat the last operation.
With + or −, % uses a percentage of the running total. With × or ÷, % divides the entry by 100.
MC clears memory, MR recalls it, MS stores the displayed value, and M+ adds to it. C clears the calculation; CE clears the current entry. Memory survives C.
Enter or = calculates; Escape clears; Delete clears the entry; F9 changes the sign. Ctrl+V pastes a number. Both modes calculate locally in your browser.
