- [Array Shuffle](https://elysiatools.com/en/tools/array-shuffle): Randomly shuffle array elements with support for different shuffling algorithms and reproducible results
- [Coin Flipper](https://elysiatools.com/en/tools/coin-flipper): Flip a virtual coin with multiple coins option
- [Color Generator](https://elysiatools.com/en/tools/color-generator): Generate random colors and color palettes
- [Decision Maker](https://elysiatools.com/en/tools/decision-maker): Make decisions by randomly selecting from options or flipping a coin
- [Deck Shuffler](https://elysiatools.com/en/tools/deck-shuffler): Shuffle a standard deck of playing cards
- [Dice Roller](https://elysiatools.com/en/tools/dice-roller): Roll virtual dice with various configurations
- [Ed25519 / X25519 Keygen and Signature Verifier](https://elysiatools.com/en/tools/ed25519-x25519-keygen-signature-verifier): Generate Ed25519 or X25519 keypairs from random or deterministic seed text, then sign or verify messages
- [Lottery Number Generator](https://elysiatools.com/en/tools/lottery-number-generator): Generate random lottery numbers for various countries and lottery types
- [Maze Generator](https://elysiatools.com/en/tools/maze-generator): Generate random mazes with customizable size and difficulty
- [Monte Carlo Simulation Builder](https://elysiatools.com/en/tools/monte-carlo-simulation-builder): Define input distributions (normal/uniform/lognormal/triangular), write a formula, run thousands of trials, and get the output distribution histogram with confidence intervals.
- [Numeric OTP Generator](https://elysiatools.com/en/tools/otp-generator): Generate cryptographically secure one-time numeric codes (SMS / email verification, raffle codes, event pins) with configurable length (3-10 digits), bulk output, optional ambiguous-digit exclusion, and an optional expiry countdown. Uses crypto.randomInt, not Math.random.
- [Password Generator](https://elysiatools.com/en/tools/password-generator): Generate secure random passwords
- [PDF Denoise](https://elysiatools.com/en/tools/pdf-denoise): Remove visual noise from scanned PDF pages — salt-and-pepper speckle, random grain, and faint background haze — using real image-processing algorithms. Text pages are preserved as searchable vector content.
- [PKCE Code Verifier & Challenge Generator](https://elysiatools.com/en/tools/pkce-code-verifier-generator): Generate, validate and verify OAuth2 / OIDC PKCE (RFC 7636) code_verifier and S256 code_challenge pairs. Three modes: (1) generate a fresh verifier + challenge from cryptographically secure random bytes at 256/384/512/768-bit entropy, (2) audit a verifier you already have against the RFC — length (43–128), charset \[A-Za-z0-9-._~\] and ≥256-bit entropy, and (3) verify a verifier/challenge pair by recomputing BASE64URL(SHA256(verifier)). Optionally build the full authorization-request URL and token-exchange body. Complements the generic nonce-generator (which only emits a verifier+challenge pair) with RFC-compliance auditing and pair verification.
- [Poker Outs and Equity Simulator](https://elysiatools.com/en/tools/poker-out-simulator): Simulate Texas Hold'em equity against random opponents, estimate win and tie rates, and list next-card improvement outs
- [Random Card](https://elysiatools.com/en/tools/random-card): Draw random playing cards from a standard deck
- [Random Group Generator](https://elysiatools.com/en/tools/random-group-generator): Randomly group input data into specified number of groups with flexible options
- [Random Lottery](https://elysiatools.com/en/tools/random-lottery): Random lottery system for selecting winners from participant list
- [Random Number Generator](https://elysiatools.com/en/tools/random-number-generator): Generate random numbers with various distributions
- [Random String Generator](https://elysiatools.com/en/tools/random-string-generator): Generate random strings with customizable character sets, length, and patterns
- [Randomize Letters in Text](https://elysiatools.com/en/tools/randomize-letters): Quickly randomize the order of letters in text
- [Randomize Text Lines](https://elysiatools.com/en/tools/randomize-text-lines): Quickly randomize the order of lines in text
