Build Your Own

Players drag a pipe from each endpoint to its matching partner until every square is filled, and a bridge square lets one pipe cross another without touching it. Pick the difficulty, how many boards must be finished, and a color theme. You do not lay out the boards: they come from a bank that was checked in advance for a single solution, so no cache can ship an impossible puzzle. The server validates the finished routes, so your final coordinates or keyword are never in the page.

Players swipe through the letters on a wheel to spell words, and every word they find fills itself into a small crossword. Pick the difficulty, how many crosswords they must finish, and whether hints are offered. You do not write the words: the puzzles come from a bank of 2,000 that were checked in advance, so no cache can ship an impossible board. Only the blank grid and the wheel letters are ever sent to the browser, and the server checks every word, so your final coordinates or keyword are never in the page.

Players swipe to slice cache containers thrown up in arcs, one point each, but muggles fly through the same arcs and slicing three of those ends the run on the spot. Beat the target score before the last volley lands and the cache is revealed. The round is served one volley at a time and audited on the server, so it cannot be precomputed or faked.

Players slide a board of 1s, 2s and multiples of three one cell at a time, joining a 1 and a 2 into a 3 and matching tiles from there, until they build the goal tile you pick (48 up to 384). Only a real, server-verified game reveals your final coordinates or keyword, so the answer never sits in the page and a faked win will not pass.

Players drop geocaching symbol tiles into a narrow well, where matching tiles merge and the pile settles into chains, until they build the goal tile you pick. Only a real, server-verified run reveals your final coordinates or keyword, so the answer never sits in the page and a faked win will not pass.

Players steer a trail around the board collecting cache containers, dodging litter and their own tail, with optional power-ups. Collect the number you set and the cache is revealed. Only a real, server-verified run reveals your final coordinates or keyword, so the answer never sits in the page and a faked win will not pass.

Players whack the critters popping out of the holes, one point each, but a cache container costs them two, so aim matters as much as speed. Beat the target score before the clock runs out and the cache is revealed. The round is served one wave at a time and scored on the server, so it cannot be precomputed or faked.

Players take on a computer opponent at American checkers, and only beating it unlocks your final coordinates or keyword. Pick the difficulty, from a gentle opponent that blunders now and then up to one that searches nine moves ahead, choose which side the finder plays, and pick one of five illustrated boards: a geocaching set of ammo cans against film canisters on a topographic map, carved wood, deep space, a tide pool, or a night market. Every move is judged on the server against its own copy of the board, so the game cannot be won from the console and your reveal is never in the page.

Players tap to keep a bird flapping through gap after gap in the pipes, and only a run that passes your pipe target unlocks your final coordinates or keyword. Pick how many pipes they have to clear, from 5 up to 100. Every run is replayed on the server before anything is unlocked, so a claimed score proves nothing on its own and your reveal is never in the page. Flappy games are hard, so a modest target goes a long way.

Players hop a chicken across lane after lane of traffic, and only a run that reaches your lane target unlocks your final coordinates or keyword. Pick how far they have to get, from 20 lanes up to 200. The road is dealt fresh for every player and every run is replayed on the server before anything is unlocked, so a claimed score proves nothing on its own and your reveal is never in the page.

Shapes flash up around the board and players have to tap the squares while leaving the circles alone. A square scores a point, a circle costs two and freezes the scoring for a moment, so tapping everything in sight loses badly. Pick the target score and whether the round runs 30, 60 or 90 seconds. Every tap is replayed on the server before anything is unlocked, so a claimed score proves nothing on its own and your reveal is never in the page.

Players hop a frog up through the traffic, then ride the logs across the river to reach the lily pads at the top. Only a run that completes your number of crossings unlocks your final coordinates or keyword. Pick how many crossings they need, from 1 up to 20. The board is dealt fresh for every player and every run is replayed on the server before anything is unlocked, so a claimed score proves nothing on its own and your reveal is never in the page.

Players clear a hidden minefield, and only a fully cleared field unlocks your final coordinates or keyword. Pick the size, from a 9x9 field with 10 mines up to a 30x16 expert field with 99, and pick a balloon or classic look. Every field is dealt fresh on the server for each player and is guaranteed solvable by logic alone, so nobody has to guess and the answer is never in the page.

Players defend six cities and three missile batteries from waves of incoming warheads, tapping to fire counter missiles that leave a fireball where they burst. Every level rebuilds the skyline and refills the batteries, and the waves come faster each time. Only a run that clears your number of levels with something still standing unlocks your final coordinates or keyword. Pick how many levels they need, from 3 up to 20. Every shot is replayed on the server before anything is unlocked, so a claimed score proves nothing on its own and your reveal is never in the page.

Players drag out every word you hide in a letter or number grid, and only a completely cleared list unlocks your final coordinates or keyword. Type your own words, pick a 12x12, 15x15 or 18x18 grid, and choose whether words may run diagonally or backwards. The grid is built fresh on the server for every player and your reveal is never in the page.

Players fly a ship up a scrolling starfield, shooting down waves of aliens on the difficulty and lives you choose. Clearing the level reveals your final coordinates or keyword. Every clear is verified by replaying the run on the server, never trusted from the page.

Players drive a marker through a procedural maze from the top left start to the bottom right exit, a fresh maze every play. Reaching the exit reveals your final coordinates or keyword and reports the server-measured time it took. Set an optional time limit, the clock runs on our server so it cannot be cheated.

Players slide numbered tiles around a grid to put them back in order, one move at a time around the single empty space. Solving the classic 15 puzzle reveals your final coordinates or keyword. Pick the grid size, 3x3 up to 5x5. Every winning run is replayed and checked on the server, never in the page.

Players jump pegs over each other on the classic 15 hole triangle board, removing the jumped peg each time, trying to finish with a single peg left. Winning it down to one peg reveals your final coordinates or keyword. The whole move log is replayed and checked on the server, never in the page.

Players fill a grid with two colours so every row and column balances, with no three of a colour in a row and no two rows or columns alike. Pick which grid sizes to include, from 4x4 up to 10x10, and clearing them all in order reveals your final coordinates or keyword. A fresh, uniquely solvable puzzle is generated on the server for every player, so the answer is never in the page.

Players place their own fleet, then duel a computer opponent that fires back after every shot they take. Sinking every enemy ship reveals your final coordinates or keyword. The enemy fleet is dealt fresh on the server and never sent to the page, so nothing can be seen ahead of time.

Players clear a paddle-and-ball brick breaker, bouncing the ball to smash bricks, catch power ups like fireball and multiball, and fight through the levels you choose. Clearing the level goal you set reveals your final coordinates or keyword. Every level clear is checked on the server, never in the page.

Players flood a 14 by 14 grid with one color at a time, starting from the top left corner, until the whole board matches within the move budget you set. Flooding the board reveals your final coordinates or keyword. Every winning run is replayed and checked on the server, never in the page.

Players watch a melody of colored pads light up one step at a time and play it back, with one more step added each round they get right. Playing back the number of rounds you set in a row reveals your final coordinates or keyword. Every round is checked on the server, and one wrong tap ends the run, but there is no limit on tries.

Players remove equal digits or pairs that total 10 along clear rows, columns, diagonals, and row wraps. Clearing the full board reveals your final coordinates or keyword. Every run is replayed on the server before the protected answer is released.

Build a quest of missions, trivia, ciphers, riddles, and GPS check-ins, each worth points. Players work through them in any order the unlock rules allow, and crossing your point goal reveals the final coordinates or keyword. Add hints with a point cost and mark missions required. Everything is checked on the server, never in the page.

Upload a zoomed-in map photo with a red mark on a hidden spot, and players work out where it is and submit the coordinates. Land close enough to the mark and your final coordinates or keyword are revealed. The secret location is checked on the server and never sits in the page.

Players guess your secret word or phrase one letter at a time before their guesses run out. Pick one of six perils, from the classic gallows to walking the plank, a launching rocket or a draining GPS, and set the difficulty. Solving it reveals your final coordinates or keyword, or let a fresh word be picked daily. The word is checked on the server, never in the page.

Players take on the computer at Connect 4. Getting four in a row before it does reveals your final coordinates or keyword. Choose geocaching cache-type discs or classic two-colour pegs, a difficulty, and who moves first. The whole game runs on the server, so there is nothing on the page to peek at.

Players view a satellite map and drop a pin to guess a hidden location, getting warmer or colder feedback, from freezing to on fire, with every check. Landing inside the radius you set reveals your final coordinates or keyword. The hidden spot is checked on the server and never sits in the page.

Battleship on a map: players fire guesses at a hidden location and each shot reports only the range it landed in, like less than 500 m or more than 2 miles, never the exact distance or direction. Past shots stay pinned so players triangulate and zero in. Landing inside the radius you set reveals your final coordinates or keyword. The hidden spot is checked on the server and never sits in the page.

Players slide and merge geocaching symbol tiles until they build the goal tile you pick (256 up to 2048). Only a real, server-verified game reveals your final coordinates or keyword, so the answer never sits in the page and a faked win will not pass.
