Quadrivium vs Odin's Drop 4+

Four logic puzzles on one square grid. Futoshiki, Skyscrapers, Magic Square and Calcudoku share the same board. In three of them every digit appears once per row and column, and the Magic Square uses every number exactly once. What differs is the clue around the grid: the signs between two cells, the numbers along the edge, the sum of every line, the target of a cage. Every puzzle is generated when you start it. You choose the size and the level, and for Calcudoku also which operations appear and how large a cage may grow. The hint never leaves you stuck. It names the rule that applies right now and shows the cells it applies to. Every puzzle the app builds can be solved with the techniques of its own level: no guessing, no dead ends. A daily puzzle, one puzzle type per weekday. Statistics, achievements, ten color worlds, and a newspaper world of its own on iPad. No account, no ads, no tracking. What you play stays on your device. I build this on my own: every rule, every hint, all 45 languages, one desk. No studio behind me, no ads, no tracking, no subscription. Write to me and a person answers. Happy puzzling, Tobias

No Ads, No Subscriptions, No Tracking. Odin’s Drop 4+ is the drop game four ways, from three in a row on a small board made for young players to six in a row across eleven columns. Pick a column and your coin falls as far as it can. One price, the whole game. No in-app purchases, no third-party ads, and no tracking. PLAY TOGETHER, YOUR WAY Live online: challenge a friend and trade moves in real time. Turn-based online: play at your own pace without being online together. Nearby: connect device to device and play without a Game Center account. Pass & Play: share one screen and take turns. In a live or nearby rematch the sides swap, so nobody keeps the opening. Online matches use Game Center. Turn notifications and a Home Screen widget show when you have moves waiting, and Siri can continue your game. OPTIMIZED FOR IPHONE DUO Open the phone and the board fills the inner display; close it and your game carries on, on the outer display, right where you were. FOUR BOARDS, ONE RULE Drop a coin and it falls to the lowest free cell in its column. Line up enough of your coins in a row, column, or diagonal and you win; a full board with no line is a draw. Drop Three: five columns, five rows, three in a row. Made for the youngest players. Drop Four: seven columns, six rows, four in a row. The classic. Drop Five: nine columns, seven rows, five in a row. More room, longer plans, and a single threat is never enough. Drop Six: eleven columns, eight rows, six in a row. A long game of threats stacked on threats. Bigger boards are worth more XP. HOUSE RULES Runestones: a few neutral runestones land on the board before play. Every game opens from a different position, and no line runs through a stone. Undertow: on your turn, drop a coin or pull one of your own from the bottom row, and the whole column sinks. A full board is not the end; when a position repeats three times, the game is a draw. Turn either one on, or both, from House Rules on the main menu. They work in every mode, and a turn-based or nearby invitation names them before your friend accepts. A NEW PAIR OF COINS EVERY GAME The coins are painted Viking portraits, a hundred of them from the longhouse of Odin’s Viking Chess, and every game deals a fresh pair. Or pick another look in Settings: engraved faces, Viking runes or checkers pieces. FIND YOUR CHALLENGE Play solo against four computer strengths: Easy, Medium, Hard, and Expert.
