Dicey is a powerful, on-device toolkit built for TTRPG designers and Game Masters who want to truly understand their dice mechanics. Go beyond simple rolling — Dicey's Monte Carlo simulation engine runs 20,000 iterations in the background to reveal probability distributions, percentiles, and success rates for even the most complex dice pools. ======= Features ======= * Comprehensive Dice Support: Roll standard polyhedral dice including d4, d6, d8, d10, d12, d20, and d100. * Advanced Dice Mechanics: Exploding Dice, Automatically reroll 1s or reroll results below a custom threshold, Keep/Drop the highest or lowest 'N' dice from your pool. * Success Conditions: Set complex target conditions such as "Sum meets/over target," "Sum below Target," or count occurrences of a specific face. * Monte Carlo Simulation Engine: Runs up to 20,000 iterations in the background to instantly estimate average yields, standard deviations, and success probabilities. * Visual Data & Comparison: Pit two configurations against each other in Opposed Roll mode to see win rates, victory margins, and head-to-head distributions at a glance — building each pool is as simple as tapping to focus a side, then tapping dice to add. Save any setup as a snapshot and overlay multiple distributions in the Compare tab to fine-tune your system's balance. * Roll History: Keeps a detailed ledger of your recent rolls, including the exact mechanics used, success states, and modifiers.

This update focuses on making Dicey feel smoother and less cramped across every tab: — Sandbox Redesign: The statistics panel and Roll button are no longer pinned to the bottom of the screen. Average, standard deviation, percentiles, and roll results now flow naturally as you scroll, giving you much more room to work with your dice pool and distribution chart. — Safer Chart Interaction: Dragging the target line on the distribution chart is now clamped to the actual data range, preventing accidental runaway values that could freeze the app. — Faster Opposed Roll Building: Tap a pool to focus it, then tap dice to add — no more per-die menus. The focused pool is clearly highlighted so you always know where dice are going. — Target Finder Cleanup: The condition picker has been moved from a tight segmented bar to a clean dropdown menu, making it easier to read and select on any screen size.
