opposition vs Vitric

Opposition was invented as a board game in the 1970’s by Bob Packard, a high school math teacher from Alaska. Bob was my father. He made game boards out of mahogany in his wood shop, then he’d take my brother & me to school where we’d play against his students. I brought the game to the iPad and iPhone.

Vitric is a calm glass-shatter puzzle for iPhone and iPad. A pane of glass fractures into a field of unique shards. Each shard belongs to exactly one place. Drag pieces from the scatter tray, line them up, and watch each one lock home with a soft green glow. When the last shard settles, the pane is whole again. Every level is built solution-first, so it is always solvable — no dead ends, no impossible boards, no luck. The challenge is finding where each piece belongs. A GENTLE, GROWING CHALLENGE The difficulty rises one mechanic at a time, so the game teaches itself: • Early levels — slide shards straight into place • Then rotation unlocks, snapped to clean 90° turns • Then free rotation at any angle • Finally horizontal flips, for shards that are mirrored Piece counts climb alongside each new mechanic, so the curve stays smooth from your first pane to your hundredth. EARN YOUR STARS Solve in few moves to earn three stars. The threshold scales with the size of the puzzle, so a big, busy pane is just as winnable for three stars as a small one — efficiency is rewarded, not raw speed. Your best star count is kept for every level. PLAY AT YOUR OWN PACE There is no timer and no failure state. Put it down mid-puzzle and it will be exactly where you left it when you return — Vitric resumes the right level and the exact arrangement of your pieces. BUILT FOR EVERY HAND • One-finger controls throughout — drag to move, on-screen buttons to rotate and flip. No multi-finger gestures required. • An optional placement guide shows a faint outline of each shard's home for an easier, lower-pressure solve. • Sound effects can be turned off independently; gentle haptics stay on either way. PRIVACY, RESPECT, SIMPLICITY Vitric contains no third-party analytics SDK, no advertising, no account system, and no network code. Nothing leaves your device. The app runs in airplane mode exactly the same as online. It is free, with no in-app purchases and no subscriptions. iPhone and iPad. iOS 26.5 or later. If Vitric becomes part of your quiet few minutes — on a commute, in a waiting room, before sleep — we'd love to hear from you.
