Editor review
Wave Codex pairs a four-rule logic grid with a tiered difficulty curve and a small set of progression milestones. The progression is the design choice that lifts the title above the usual sudoku-clone. You unlock new rule combinations as you clear tiers, which means a returning player encounters fresh interactions rather than the same rules at a higher cell count.
The hint button gives one cell per board. Used hints reduce the score by ten percent. That trade is reasonable; players who hate hint pressure will leave it alone and players who want progress can rent themselves out of a stuck board.
Played over a week, mostly on Edinburgh Edinburgh tram rides. The boards fit the session length and the auto-save handles mid-board state correctly.
The flaw is the soundtrack. The ambient track loops over a short interval and starts to grate by board ten. Mute and play with phone audio off. Four stars; the puzzle work is the strongest section and the audio is the weakest.
